TECHNICAL FIELD

Devices, systems, and methods herein relate to manufacturing cellproducts for biomedical applications using automated systems.

BACKGROUND

Cellular therapies based on hematopoietic stem cells (HSCs), chimericantigen receptor (CAR) T cells, NK cells, tumor infiltrating lymphocytes(TILs), T-cell receptors (TCRs), regulatory T cells (T regs), gammadelta (γδ) T cells, and others rely on manufacturing of cell products.Manufacturing of such cell products typically involves multiple cellprocessing steps. Conventional solutions for manufacture of cellproducts rely on cumbersome manual operations performed in expensivebiosafety cabinets and/or clean rooms. Skilled laboratory technicians,adequate sterile enclosures such as cleanroom facilities, and associatedprotocols and procedures for regulated (GMP) manufacturing areexpensive. Many current manufacturing processes employ numerous manualreagent preparation and instrument manipulation steps during amanufacturing protocol, and the processes may require several days oreven weeks. Even platforms described as automated cell processing in aclosed system generally rely on pre-configured instrumentation andtubing sets that limit operational flexibility and do not reliablyprevent process failure due to accidental operator/human error.

Most efforts to automate cell product manufacturing have been directedto automating individual processing steps of a cell therapymanufacturing workflow. Even systems that automate several steps lackend-to-end process flexibility, process robustness, and processscalability. These and other limitations of the previous attempts atautomation of cell processing are addressed in various embodimentsdisclosed here.

DETAILED DESCRIPTION

Systems and methods for processing and manufacturing cell products forbiomedical applications are described herein. Cell processing methodsand systems may comprise moving a cartridge containing a cell productbetween a plurality of instruments inside a workcell. One or moreinstruments may be configured to interface with the cartridge to performcell processing steps on the cell product, such that the system (e.g.,workcell) performs cell processing steps on the cell product. In somevariations, a plurality of cell processing steps may be performed withina single cartridge. For example, a robotic arm may be configured to movea cartridge between instruments for different cell processing steps. Thecartridge may comprise a plurality of cell processing devices (e.g.,modules) such as a bioreactor, a counterflow centrifugal elutriation(CCE) module, a magnetic cell sorter (e.g., magnetic-activated cellselection module), an electroporation device (e.g., electroporationmodule), a sorting module (e.g. fluorescence activated cell sorting(FACS) module), an acoustic flowcell module, a centrifugation module, amicrofluidic enrichment module, combinations thereof, and the like. Insome variations, the system may process two or more cartridges inparallel. For example, the bioreactor may comprise a plurality of slotsconfigured to interface with a plurality of cartridges concurrently, asone process step (e.g., cell culturing in a bioreactor) may typically bethe rate limiting step for the operation of the cell processing system.The cell processing systems described herein may reduce operatorintervention and increase throughput by automating cartridge (and cellproduct) movement between instruments using a robot. However, in somevariations, the cartridge may be moved between instruments manually.Furthermore, throughput of the system may be increased by using aplurality of bioreactors, thereby allowing the system to simultaneouslyprocess a plurality of cartridges for a plurality of patients. Moreover,the automated cell processing system may facilitate sterile liquidtransfers between the cartridge and instruments or other components ofthe system such as a fluid connector (e.g., sterile liquid transferport), reagent vault, a second cartridge, a sampling vessel (e.g.,sterile liquid transfer device, combinations thereof, and the like.

Workcell

In some variations, a system for cell processing (e.g., workcell) maycomprise a plurality of instruments each independently configured toperform one or more cell processing operations upon a cartridge. A robotmay be configured to move the cartridge between each of the plurality ofinstruments. The instruments may comprise one or more of a bioreactorinstrument, a cell selection instrument (e.g., a magnetic-activated cellselection instrument), a sorting instrument (e.g., a fluorescenceactivated cell sorting (FACS) instrument), an electroporationinstrument, a counterflow centrifugal elutriation (CCE) instrument, areagent vault, and the like. The system may perform automatedmanufacturing of cell products.

A cartridge may be configured to be portable and facilitate automatedand sterile cell processing using a workcell and robot. For example, thecartridge may be configured to move relative to one or more instrumentsof the workcell to perform different cell processing steps. In somevariations, an instrument may be configured to move relative to acartridge. In some variations, the cartridge may comprise a plurality ofmodules including one or more of a bioreactor module, a cell selectionmodule (e.g., magnetic-activated cell selection module), a sortingmodule (e.g., fluorescence activated cell sorting (FACS) module), anelectroporation module, and a counterflow centrifugal elutriation (CCE)module. The cartridge may further comprise one or more of a sterileliquid transfer port, a liquid transfer bus fluidically coupled to eachmodule, and a pump fluidically coupled to the liquid transfer bus.

In some variations, a method of processing a solution containing a cellproduct may include the cell processing steps of digesting tissue usingan enzyme reagent to release a select cell population into solution,enriching cells using a CCE instrument, washing cells using the CCEinstrument, selecting cells in the solution using a selectioninstrument, sorting cells in the solution using a sorting instrument,differentiating or expanding the cells in a bioreactor, activating cellsusing an activating reagent, electroporating cells, transducing cellsusing a vector, and finishing a cell product.

Cell Selection System

The cell processing systems described herein may comprise a cellselection system configured to separate cells based on predeterminedcriteria. For example, cells may be separated based on physicalcharacteristics such as size and/or density using, for example, acounterflow centrifugation elutriation instrument. Cells may also beseparated based on the presence of predetermined antigens of a cellusing, for example, a magnetic-activated cell selection instrument. Insome variations, a cell selection system comprising modules for theseseparation methods may facilitate one or more cell processing stepsincluding, but not limited to, cell concentration, cell dilution, cellwashing, buffer replacement, and magnetic separation. The cell selectionsystems described herein may increase throughput and cell yields output,in a compact and portable structure. For example, prior to magneticallyseparating cells, a suspension of cells may be mixed with magneticreagents in excess or at a predetermined concentration (e.g., cells/ml).Likewise, after magnetically separating cells, the cells may be washedin a solution (e.g., suitable buffered solution).

In some variations, a cell separation system may comprise a rotorconfigured for counterflow centrifugation elutriation of cells in afluid, a first magnet configured to magnetically rotate the rotor andseparate the cells from the fluid in the rotor, a flow cell in fluidcommunication with the rotor and configured to receive the cells fromthe rotor, and a second magnet configured to magnetically separate thecells in the flow cell.

In some variations, a CCE module may be integrated into a cartridge toenable a cell processing system to separate cells based on cell sizeand/or density. In some variations, a cell separation system maycomprise a housing comprising a rotor configured to separate cells froma fluid (e.g., separate cells of different size and/or density fromcells that remain in the fluid), and a magnet configured to magneticallyrotate the rotor. The housing may be configured to move relative to themagnet or vice versa (e.g., move the magnet relative to the housing).The CCE modules described herein may provide cell separation within acompact and portable housing where the magnet may be disposed externalto the housing (e.g., magnet disposed within a CCE instrument).

In some variations, a compact rotor that may aid cartridge integrationmay comprise input and output fluid conduits extending from the rotortowards opposing sides of a rotor housing. For example, a rotor maycomprise a first side comprising a first fluid conduit and a second sidecomprising a second fluid conduit where the second side is opposite thefirst side. An elutriation chamber (e.g., cone) may be coupled betweenthe first fluid conduit and the second fluid conduit.

In some variations, a method of separating cells from a fluid maycomprise moving a rotor towards a magnet, the rotor defining arotational axis, flowing the fluid through the rotor, rotating the rotor(e.g., magnetically) about the rotational axis using the magnet whileflowing the fluid through the rotor, and moving the rotor away from themagnet.

In some variations, a method of separating cells from a fluid maycomprise flowing the fluid comprising the cells into a flow cell. A setof the cells may be labeled with magnetic particles. The set of cellsmay be magnetically attracted towards a magnet array for a dwell time,and the set of cells may flow out of the flow cell after the dwell time.

In some variations, a flow cell may comprise an elongate cavity having acavity height and a magnet array comprising a plurality of magnets, eachof the magnets spaced apart by a spacing distance. A predetermined ratiobetween the cavity height to the spacing distance may optimize magneticseparation of the cells in the flow cell.

Electroporation

In some variations, an electroporation module as described herein may beconfigured to facilitate one or more of transduction and transfection ofcells. As described in more detail herein, a volume of fluid (e.g.,first batch) comprising cells may be physically separated from asubsequent volume of fluid (e.g., second batch, third batch) comprisingcells by a gas (e.g., air gap). Applying an electroporation signal(e.g., voltage pulse, waveform) separately to each discrete batch offluid may improve electroporation efficiency and thus increasethroughput. In some variations, active electric field compensation maysimilarly improve electroporation efficiency and throughput.

In some variations, a cell processor may comprise a fluid conduitconfigured to receive a first fluid comprising cells and a second fluid(e.g., gas, oil), a set of electrodes coupled to the fluid conduit, apump coupled to the fluid conduit, and a controller comprising aprocessor and memory. The controller may be configured to generate afirst signal to introduce the first fluid into the fluid conduit usingthe pump, generate a second signal to introduce the second fluid intothe fluid conduit such that the second fluid separates the first fluidfrom a third fluid, and generate an electroporation signal toelectroporate the cells in the fluid conduit using the set ofelectrodes.

In some variations, a method of electroporating cells may comprisereceiving a first fluid comprising cells in a fluid conduit, receiving asecond fluid comprising a gas in the fluid conduit to separate the firstfluid from a third fluid, and applying an electroporation signal to thefirst fluid to electroporate the cells.

In some variations, a method of electroporating cells may comprisereceiving a first fluid comprising cells in a fluid conduit, applying aresistance measurement signal to the first fluid using a set ofelectrodes, measuring a resistance between the first fluid and the setof electrodes, and applying an electroporation signal to the first fluidbased on the measured resistance.

Bioreactor

In some variations, a bioreactor may comprise an enclosure comprising abase and a sidewall, and a gas-permeable membrane coupled to one or moreof the base and the sidewall of the enclosure. The gas-permeablemembrane may aid cell culture. In some variations, a cell processingsystem may comprise the bioreactor and an agitator coupled to thebioreactor. The agitator may be configured to agitate the bioreactorbased on orbital motion.

Fluid Connector

Currently, there is no automated, multi-use sterile fluid connectorsolution for cell therapy production where a set of sterile fluidconnectors are capable of multiple connection and disconnection cycleswith a system. For example, conventional sterile fluid connectors aretypically single-use devices and are thus expensive and labor intensive.Generally, the fluid connectors described herein include a plurality ofsealed enclosures between a sterile portion (e.g., fluid connector lumenor cavity) and an external (e.g., non-sterile) ambient environment,thereby facilitating aseptic control of a fluid connector and devicescoupled thereto. The fluid connectors described herein may be a durablecomponent that may be reused for multiple cycles while maintainingsterility and/or bioburden control. For example, the fluid connector maybe sterilized using a sterilant without harming the cell product orother biological material.

In some variations, a sterile manufacturing system as described hereinmay utilize one or more sterile fluid connectors and have aconfiguration suitable to be manipulated by a robot such as a roboticarm. The sterile fluid connectors described herein enable the transferof fluids in an automated, sterile, and metered manner for automatingcell therapy manufacturing. Automating cell therapy manufacturing may inturn provide lower per patient manufacturing costs, a lower risk ofprocess failure, and the ability to meet commercial scale patient demandfor cell therapies. In some variations, sterile fluid connectors mayincrease one or more of sterility, efficiency, and speed by removing ahuman operator from the manufacturing process. An automated andintegrated sterilization process as described herein may be applied tothe fluid connector to maintain sterility of the system. For example,the fluid connector may maintain sterility through multipleconnection/disconnection cycles between separate sterile closed volumefluid devices (e.g., enclosure, container, vessel, cartridge,instrument, bioreactor, enclosed vessel, sealed chamber). Accordingly,the systems, devices, and methods described herein may reduce thecomplexity of a sterilization process, reduce energy usage, and increasesterilization efficiency.

In some variations, a fluid connector may comprise a first connectorconfigured to mate with a second connector (e.g., male connector andfemale connector). Respective proximal ends of the connectors may beconfigured to connect (e.g., be in fluid communication, form a fluidpathway) with respective fluid devices in order to transfer one or moreof fluid (e.g., liquid and/or gas) and biological material (e.g., cellproduct) between the fluid devices. The distal ends of the connectorsmay comprise ports configured to mate with each other. The fluidconnector may also comprise a sterilant port configured to facilitatesterilization of a chamber within the distal ends of the first andsecond connectors. The fluid connector may be sterilized before or afterconnection as desired to ensure sterility. In this manner, the fluidconnector may be reused for multiple connection and disconnectioncycles.

In some variations, a system (e.g., workcell) utilizing the fluidconnectors described herein may comprise a robot configured to operatethe fluid connector and a controller configured to control the robot tomanipulate (e.g., move, connect, open, close, disconnect) the first andsecond connectors together (without human interaction) while maintainingsterility of the fluid connector and a plurality of fluid devices,thereby further reducing the risk of contamination. The fluid devicesmay be one or more of an instrument, cartridge, and the like.

Cell Processing Control

Systems and methods for manufacturing cell products for biomedicalapplications using automated systems are described herein. Conventionalsemi-automated solutions for cell processing do not allow users todefine biological processes. Instead, users select from a limited set ofpredefined machine processes and process-control parameters. Currently,there is no scalable manufacturing solution for cell therapy production.For example, cell therapy manufacturing is conventionally executedbatchwise (i.e. one product will be manufactured in a single room/suite,with required processing tools located inside). This can either beguided by a technician following a standard operating procedure (SOP),or in some cases, processing tools (e.g., Miltenyi Prodigy, LonzaCocoon) can carry out a series of processing steps for a single patientproduct on a single multi-functional processing tool. However, existingsolutions (e.g., Miltenyi Prodigy) do not allow users to definebiological processes. Furthermore, the manual labor required ofconventional solutions increases the risk of product contamination andhuman error.

In some variations, a set of cell therapy biological manufacturingprocesses may be transformed into a set of machine instructions suitablefor automated execution using the systems described herein. For example,a method of transforming user-defined cell processing operations intocell processing steps to be executed by a processor of an automated cellprocessing system may comprise receiving an ordered input list of cellprocessing operations, and executing a transformation model on theordered input list to create an ordered output list of cell processingsteps capable of being performed by the system. As used herein, atransform model may refer to an algorithm, process, or transformationconfigured to translate a set of cell processing steps into a set ofmachine or hardware instructions for the system. In some variations, arobot may be controlled to move one or more cartridges each containing acell product between the instruments, and the instruments may becontrolled to perform cell processing steps on each cell product. Inthis manner, the systems and methods enable biologists to definemanufacturing processes in biological terms and have the systemtransform this biological model (e.g., process definition) into a set ofmachine-executed instructions.

The end-to-end closed system automation described herein may reduceprocess failure rates and cost. For example, end-to-end automation mayreduce manufacturing time (e.g., dwell times) and increase throughput ascompared to conventional manual methods. For example, a plurality ofprocesses (e.g., 10 or more) may be executed simultaneously. The methodsdescribed herein may further reduce opportunities for contamination anduser error. Thus, the systems, apparatuses, and methods described hereinmay increase one or more of cell processing automation, repeatability,reliability, process flexibility, instrument throughput, processscalability, and reduce one or more of labor costs, and processduration.

I. SYSTEM

In some variations, the workcell may be an open system lackingan enclosure, which may be configured for use in clean room, biosafetycabinet, or other sterile location. In some variations, the cartridge114 may be moved using the robot 116 to reduce manual labor in the cellprocessing steps.

In some variations, the enclosureof the workcell may be configured to meet International Organization forStandardization (ISO) standard ISO7 or better (e.g., ISO6 or ISO5). Anadvantage of meeting ISO7 or better standards is that the system may beused in a facility that does not meet IS07 standards (i.e. that lack aclean room or other sufficiently filtered air space). Optionally, thefacility may be an ISO8 or ISO9 facility. In some variations, a workcellmay comprise a volume of less than about 800 m³, less than about 700 m³,less than about 600 m³, less than about 500 m³, less than about 300 m³,less than about 250 m³, less than about 200 m³, less than about 150 m³,less than about 100 m³, less than about 50 m³, less than about 25 m³,less than about 10 m³, and less than about 5 m³, including all rangesand sub-values in-between.

In some variations, a robot 116 may be configured to manipulateconsumable cartridges 114 and fluid connectors 132 between differentinstruments to perform a predetermined sequence of cell processingsteps. In some variations, the same consumable cartridge 114 may bereceived by different instruments 112 and/or multiple cartridges 114 maybe processed in parallel.

In some variations, a cartridge 114 may contain cell product fromdifferent donors or contain cell product intended for differentrecipients. The cell product from a single donor may be split betweenmultiple cartridges 114 if necessary to generate enough product fortherapeutic use, or when a donor is providing product for severalrecipients (e.g., for allogeneic transplant). The cell product for asingle recipient may be split between multiple cartridges 114 ifnecessary to generate enough product for therapeutic use in thatrecipient. The cell product for a single recipient may be split betweenmultiple cartridges 114 if necessary to generate several cell productswith unique genetic modifications, and then optionally recombined incertain ratios for therapeutic use in that recipient. For example, afluid connector 132 may be coupled between two or more cartridges 114 totransfer a cell product and/or fluid between the cartridges 114.Furthermore, a fluid connector 132 may be coupled between any set offluid-carrying components of the system 100 (e.g., cartridge 114,reagent vault 118, fluid source 136, sterile liquid transfer device 142,fluid conduit, container, vessel, etc.). For example, a first fluidconnector may be coupled between a first cartridge and a sterile liquidtransfer device, and a second fluid connector may be coupled between thesterile liquid transfer device and a second cartridge.

In some variations, a workcell 110 may comprise at least a partiallyenclosed enclosure (e.g., housing) in which one or more automated cellprocessing steps are performed. For example, the workcell 110 may beconfigured to transfer sterile liquid into and out of a cartridge 114 ina fully or partially automated process. In some variations, a workcell110 may not have an enclosure and be configured for use in a clean room,a biosafety cabinet, or other suitably clean or sterile location. Insome variations, the workcell 100 may comprise a feedthrough accessbiosafety cabinet, quality control instrumentation, pump, consumable(e.g., fluid device), fluid connector, consumable feedthrough, andsterilization system (e.g., sterilant source and/or generator, fluidsource, heater/dessicator, aerator).

The robot 230 may be configured to movethe cartridge 250 in a predefined sequence to a plurality of instrumentsand stations, with the components of the workcell 200 being controlledby the computer processor of the computer server rack 210. Additionallyor alternatively, the sequence that the cartridge 250 moves within theworkcell 200 may not be predefined. For example, cartridge 250 movementmay not be dependent on one or more of the result of a previous step,sensor value, predetermined threshold (e.g., based on a quality controlsystem), and the like. At the end of cell processing, the cartridge 250,now containing the processed cell product, may be returned to thefeedthrough 206 for retrieval by the user. Additionally oralternatively, the cell product 250 containing the processed cellproduct may be transferred (via a fluid connector) to a second cartridge(e.g., single-use cartridge) and stored in the reagent vault 226 forretrieval by the user.

Robot

Generally, a robot may comprise any mechanical device capable of movinga cartridge from one location to another location. For example, therobot may comprise a mechanical manipulator (e.g., an arm) in a fixedlocation, or attached to a linear rail, or a 2- or 3-dimensional railsystem. In a variation, the robot comprises a robotic shuffle system. Ina further variation, the robot comprises a wheeled device. In somevariations, the system comprises two or more robots of the same ordifferent type (e.g., two robotic arms each independently configured formoving cartridges between instruments). The robot may also comprise anend effector for precise handling of different cartridges or barcodescanning or radio-frequency identification tag (RFID) reading.

FIG. 5 is a perspective view of a cell processing system 500 in which arobot arm moves consumable cartridges between slots in variousinstruments each configured to perform a different cell processing step.In some variations, the same consumable cartridge can be received bydifferent instruments. The system 500 may comprise a modular design toaccommodate different instrument configurations. In some variations, aplurality of cartridges may be processed in parallel. Each cartridge maycontain a cell product from different donors or contain a cell productintended for different recipients. For example, a cell product from asingle donor may be split between a plurality of cartridges to generatea predetermined quantity of cell product for therapeutic use such aswhen a donor is providing product for several recipients (e.g., forallogeneic transplant). In some variations, the cell product for asingle recipient may be split between a plurality of cartridges togenerate a predetermined quantity of product for therapeutic use in thatrecipient. In some variations, the cell product for a single recipientmay be split between a plurality of cartridges to generate apredetermined quantity of several cell products with unique geneticmodifications, which may be recombined in certain ratios for therapeuticuse in that recipient.

Cartridge

Generally, the cell processing systems described herein may comprise oneor more cartridges including one or more modules configured to interfacewith an instrument or instruments. A robot (e.g., robotic arm) may beconfigured to move a cartridge and/or instrument to perform one or morecell processing steps. For example, a cartridge may comprise abioreactor module and/or fluid connector (e.g., sterile liquid transferport) coupled by the robot to a bioreactor instrument of a workcell.Once a predetermined processing step has been completed, the cartridgemay be moved by the robot to another instrument of the workcell, andanother cartridge may be coupled to the bioreactor instrument. Thus, aportable cartridge and shareable instruments may increase theefficiency, throughput, and flexibility of a cell manufacturing process.

In some variations, the cartridge may optionally provide aself-contained device capable of performing one or more cell processingsteps. The modules may be integrated into a fixed configuration withinthe cartridge. Additionally or alternatively, the modules may beconfigurable or moveable within the cartridge, permitting variouscartridges to be assembled from shared modules. Similarly stated, thecartridge can be a single, closed unit with fixed components for eachmodule; or the cartridge may contain configurable modules coupled byconfigurable fluidic, mechanical, optical, and electrical connections.In some variations, one or more sub-cartridges, each containing a set ofmodules, may be configured to be assembled to perform various cellprocessing workflows. The modules may each be provided in a distincthousing or may be integrated into a cartridge or sub-cartridge withother modules. The disclosure generally shows modules as distinct groupsof components for the sake of simplicity, but may be arranged in anysuitable configuration. For example, the components for differentmodules may be interspersed with each other such that each module isdefined by the set of connected components that collectively perform apredetermined function. However, the components of each module may ormay not be physically grouped within the cartridge. In some variations,multiple cartridges may be used to process a single cell product throughtransfer of the cell product from one cartridge to another cartridge ofthe same or different type and/or by splitting cell product into morecartridges and/or pooling multiple cell products into fewer cartridges.

Generally, each of the instruments of the system interfaces with itsrespective module or modules on the cartridge e.g., an electroporationmodule on the cartridge (if present) is moved by the system to anelectroporation instrument and interfaces with the electroporationinstrument to perform an electroporation step on the cell product—andmay also interface with common components, such as components of afluidic bus line (e.g., pumps, valves, sensors, etc.). An advantage ofsuch split module/instrument designs is that expensive components (e.g.,motors, sensors, heaters, lasers, etc.) may be retained in theinstruments of the system while multiple cartridges are processed. Theuse of disposable cartridges may eliminate the need, in such variations,to sterilize cartridges between use. Furthermore, the utilization ofshared instruments (e.g. electroporation instrument, CCE instrument,MACS instrument, sterile liquid transfer instrument, FACS instrument,and the like) may be increased since a plurality of the instruments maybe utilized simultaneously in parallel by a plurality of cellmanufacturing processes. In contrast, conventional semi-automatedinstruments (e.g., Miltenyi Prodigy) have instrument components that sitidle and are incapable of simultaneous parallel use.

Insome variations, flexible bags may be configured to hold large volumesand to permit transfer of fluid without replacing transferred fluid withliquid or gas to maintain the pressure in the reservoir, as the bag maycollapse when fluid is transferred out and expand when fluid istransferred in.

In some variations, the liquid transfer bus 624 may comprise valves V1to V28 and corresponding tubing that fluidically links the valves to oneanother and to each of the modules. Valves shown coupled to four fluidiclines are 4/2 (4 port 2 position) valves and valves shown coupled tothree fluidic lines are 3/2 (3 port 2 position) valves. Internal flowpaths of the valves are indicated in the legend.

The liquid transfer bus 624 may befluidically coupled to reservoir 607 d and a product bag which isfluidically coupled to STLP 606 d and to product input tubing lines 627a-627 b. An operator may input a cell product into reservoir 607 d byconnecting product input tubing line 627 a or 627 b to an externalsource of cells (e.g., a bag of cells collected from a donor). SLTP 606d may be configured to permit a system according to the disclosure(e.g., workcell 110) to add fluid to the reservoir 607 d in an automatedfashion. For example, one or more fluid-carrying containers such asreservoirs 607 a-607 k, bags, etc. may receive fluid using an SLTP.Additionally or alternatively, the SLTP may be configured toperiodically sample one or more of the fluid-carrying containers.

For example, the gasinput line 815 c may be configured for gas transfer into a fluid (e.g.,through headspace gas control or a gas-permeable membrane).

FIG. 9 shows a cross-sectional side view of a cartridge 900. In somevariations, a cartridge 900 may comprise an enclosure (e.g., housing), abioreactor 914, one or more pumps 916, valve 930, cell selection module917, and a counterflow centrifugation elutriation (CCE) module 922.

The cartridge 900 may optionallycomprise blanks configured to house additional module(s) such as a cellselection module, a cell sorting module, an electroporation module 918,and the like. In some variations, the cartridge 900 may comprise one ormore bioreactors and/or reservoirs in the blanks.

In some variations, a cartridge may comprise one or more valves. In somevariations, the valve 1000 on the cartridge may be configured to receivean actuator 1010 provided by an instrument (as shown in FIG. 10A). Asthe cartridge is inserted into the instrument, the valve 1000 may beconfigured to dock with the actuator 1010 (as shown in FIG. 10B), suchthat rotation of the actuator 1010 may cause switching of the valve 1000from one position to another position. In some variations, the valvesmay be constructed to pinch a section of soft tubing. The pinch valvesmay comprise a closed configuration, and an external actuator may beconfigured to interface with the pinch valve (e.g., utilizing a solenoidwith linear motion) to open or close the valve. The valves themselvesmay be configured to be disposable whereas the actuators may beintegrated into an instrument configured to process cartridgesrepeatedly.

Reagent Vault

In some variations, the system comprises a reagent vault (or reagentvaults) where reagents are stored including but not limited to cellculture media, buffer, cytokines, proteins, enzymes, polynucleotides,transfection reagents, non-viral vectors, viral vectors, antibiotics,nutrients, cryoprotectants, solvents, cellular materials, andpharmaceutically acceptable excipients. Additionally or alternatively,waste may be stored in the reagent vault. In some variations, in-processsamples extracted from one or more cartridges may be stored in thereagent vault. The reagent vault may comprise one or more controlledtemperature compartments (e.g., freezers, coolers, water baths, warmingchambers, or others, at e.g. about −80° C., about −20° C., about 4° C.,about 25° C., about 30° C., about 37° C., and about 42° C.).Temperatures in these compartments may be varied during the cellmanufacturing process to heat or cool reagents. In variations of themethods of the disclosure, a cartridge may be moved by the robot (ormanually by an operator) to the reagent vault. The reagent vaultinterfaces with one or more sterile liquid transfer ports on thecartridge, and the reagent or material is dispensed into the cartridge.Optionally, fluid is added or removed from the cartridge before, during,or after reagent addition or removal. In some variations, the systemcomprises a sterile liquid transfer instrument, similarly configured totransfer fluid into or out of the cartridge in an automated, manual, orsemi-automated fashion. An operator may stock the sterile liquidtransfer station with reagents manually, or they may be supplied by arobot (e.g. from a feedthrough or other location). In some cases, arobot moves a reagent or reagents from the reagent vault to the sterileliquid transfer station. The reagent vault may have automated doors topermit access by the robot for sterile liquid transfer devices and/orother reagent vessels, optionally each under independent closed looptemperature control. The devices and vessels may be configured forpick-and-place movement by the robot. In some variations, the reagentvault may comprise one or more sample pickup areas. For example, a robotmay be configured to move one or more reagents to and from one or moreof the sample pickup areas.

Various materials can be used to construct the cartridge and thecartridge housing, including metal, plastic, rubber, and/or glass, orcombinations thereof. The cartridge, its components, and its housing maybe molded, machined, extruded, 3D printed, or any combination thereof.The cartridge may contain components that are commercially available(e.g., tubing, valves, fittings); these components may be attached orintegrated with custom components or devices. The housing of thecartridge may constitute an additional layer of enclosure that furtherprotects the sterility of the cell product. The operator may performloading or unloading of the cartridge in an ISO 5 or better environment,utilizing aseptic technique to ensure that sterility of the contents ofthe cartridge is maintained when the cartridge is opened. In somevariations, the operator may perform loading or unloading of thecartridge using manual aseptic connections (e.g., sterile tube welding).The robotic system may also perform sterile loading or unloading ofliquids into and out of the cartridge through the use of the sterileliquid transfer instrument and sterile liquid transfer ports on thecartridge.

Counterflow Centrifugal Elutriation

Counterflow centrifugal elutriation (CCE) is a technique used toseparate cells based on characteristics such as size and/or density.Counterflow centrifugal elutriation combines centrifugation withcounterflow elutriation where centrifugation corresponds to the processof sedimentation under the influence of a centrifugal force field andcounterflow elutriation corresponds to the process of separation bywashing. Separation takes place in a cone (e.g., bicone, funnel) shapedelutriation chamber. Particles (e.g., cells) conveyed in a fluid intothe elutriation chamber are acted upon by two opposing forces:centrifugal force driving the fluid away from an axis of rotation; andfluid velocity driving the fluid towards the axis of rotation (e.g.,counterflow). By varying the flow rate and the centrifugal force, theseparation of particles (e.g., cells) may be achieved. For example, asdescribed in more detail herein, particles may be separated based onproperties such as size and density.

Counterflow centrifugal elutriation may perform multiple operationsuseful for cell therapy manufacturing workflows including, but notlimited to, cell washing, cell concentration, media/buffer replacement,transduction, and separation of white blood cells from other bloodcomponents (e.g., platelets, and red blood cells). In some variations, afluid source (e.g., apheresis bag) for a cell separation process maycomprise a suspension of white blood cells, red blood cells, platelets,and plasma. In order to separate immune cells of interest, white bloodcells may be isolated and subsequently magnetically tagged for magneticseparation. A white blood cell separation step may be performed in a CCEmodule to separate cells based on size and density, while magneticseparation may be performed in a MACS module. In some variations, a CCEmodule may be integrated into a cartridge to enable a cell processingsystem to separate cells based on one or more of a progression through acell cycle (e.g., G₁/M phase cells being larger than G₀, S, or G2 phasecells) and cell type (e.g., white blood cells from red blood cellsand/or platelets).

Generally, a rotor configured to spin may comprise an elutriationchamber (e.g., cone, bicone). A fluid comprising a suspension of cellsmay be pumped under continuous flow into the rotor. As cells areintroduced into the cone (e.g., bicone), the cells migrate according totheir sedimentation rates to positions in the gradient where the effectsof the two forces upon them are balanced. Smaller cells having lowsedimentation rates (e.g., platelets) may be quickly washed toward theaxis of rotation with increased flow velocity. Such smaller cells may beoutput (e.g., washed out) of the cone. Relatively larger (or denser)cells (e.g., red blood cells) flow through the cone relatively moreslowly and reach equilibrium at an elutriation boundary where thecentrifugal force and the drag force are in balance, and the fluidvelocity is relatively low because the cone has widened. The largest ordensest cells (e.g., white blood cells) remain near the inlet to thechamber where centrifugal force and fluid velocity are high. Byincreasing the flow rate in gradual steps, successive fractions ofincreasingly large or dense cells (e.g., platelets→red blood cells→whiteblood cells) may be output from the rotor. Continued incrementalincreases in fluid flow rate will eventually elutriate all cells fromthe cone.

FIG. 56 is a block diagram of a cell separation system 5600 comprising aworkcell 5610 and at least one cartridge 5620. In some variations, theworkcell 5610 may comprise one or more of a counterflow centrifugalelutriation (CCE) instrument 5632 (e.g., first magnet), amagnetic-activated cell selection (MACS) instrument 5642 (e.g., magnetarray, second magnet), a fluid connector 5652, a pump 5654, an imagingsystem comprising an optical sensor 5660 and an illumination source5662, a sensor 5664, and a processor 5670. In some variations, thecartridge 5620 may comprise one or more of a CCE module 5630 (e.g.,rotor), a MACS module 5640 (e.g., flow cell), and a fluid connector 5650(e.g., sterile liquid transfer port, liquid transfer bus). For example,a cartridge for cell processing may comprise a liquid transfer bus and aplurality of modules, each module fluidically linked to the liquidtransfer bus. The modules may include any of the CCE modules or MACSmodules described herein. In some variations, a robot (not shown) may beconfigured to move the cartridge 5620 between different locations withinthe workcell 5610 to perform different cell processing steps.

In some variations, the imaging system (e.g., optical sensor 5660,illumination source 5622) may be configured to generate image datacorresponding to one or more of the CCE module 5630 and MACS module5640. For example, image data of fluid flow through a rotor of a CCEmodule 5630 may be analyzed and used to control a flow rate of fluidand/or rotation rate of the rotor, as described in more detail herein.In some variations, the optical sensor 5660 may be a CMOS/CCD sensorhaving, for example a resolution of about 100 μm, a working distance ofbetween about 40 mm and about 100 mm, and a focal length of less thanabout 8 mm. The optical sensor 5660 may be configured to operatesynchronously with the illumination source 5662. In some variations, theoptical sensor 5660 may comprise one or more of a colorimeter, turbiditysensor, and optical density sensor. In some variations, the illuminationsource 5662 may operate as a strobe light configured to output lightpulses synchronized to a rotation rate of a rotor of the CCE module5630.

In some variations, the sensor 5664 may comprise one or more of anoptical density sensor configured to measure an intensity of fluid, aleak detector configured to detect moisture and/or leaks, an inertialsensor configured to measure vibration, a pressure sensor configured tomeasure pressure in a fluidic line (e.g., photoelectric sensor), abubble sensor configured to detect the presence of a bubble in a fluidconduit, colorimetric sensor, vibration sensor, and the like.

In some variations, the fluid connector 5652 may comprise one or morevalves, configured to control fluid flow between the workcell and thecartridge 5620. The processor 5670 may correspond to the controller(e.g., processor and memory) described in more detail herein. Theprocessor 5670 may be configured to control one or more of the CCEinstrument 5632, the MACS instrument 5642, the pump 5654, fluidconnector 5652 (e.g., valves), the optical sensor 5660, the illuminationsource 5662, and the sensors 5664.

In some variations, a system 5600 for cell processing may comprise acartridge 5600 comprising a rotor of a CCE module 5630 configured forcounterflow centrifugation elutriation of cells in a fluid. A firstmagnet of a CCE instrument 5632 may be configured to magnetically rotatethe rotor and separate the cells from the fluid in the rotor. Thecartridge may further comprise a flow cell of a MACS module 5640 coupledto the rotor and configured to receive the cells from the rotor.

In somevariations, the system 5600 may comprise one or more valves and pumps.

FIG. 57 is a cross-sectional side view of a counterflow centrifugalelutriation (CCE) module 5700 comprising a housing 5710 (e.g.,enclosure), a rotor 5720 configured to rotate within and relative to thehousing 5710, and one or more fluid ports 5730 (e.g., fluid inlet, fluidoutlet). In some variations, the CCE module 5700 may be portable andconfigured to move within a workcell 5610 and cartridge 5620. Forexample, a robot may move the CCE module 5700 between differentinstruments of a workcell 5610.

FIG. 58 is a cross-sectional side view of a magnetic-activated cellselection (MACS) module comprising a housing 5810 (e.g., enclosure), afirst fluid port 5820 (e.g., fluid inlet), a second fluid port 5830(e.g., fluid outlet), and a flow cell 5810 coupled in between the firstfluid port 5820 and the second fluid port 5830. As described in moredetail herein, the flow cell 5810 may comprise a cavity (e.g., chamber)comprising one or more channels (e.g., linear channels, laminar fluidflow channel). In some variations, the cavity of the flow cell 5810 maybe substantially empty. For example, the flow cell 5810 may be absent amesh, beads, tortuous channels, and the like. In some variations, theflow cell 5810 may have a longitudinal axis aligned perpendicular toground. That is, the flow cell 5810 may be oriented vertically where thefirst fluid port 5820 is disposed at a higher elevation than the secondfluid port 5830 such that gravity may aid fluid flow through the flowcell 5810. In some variations, the MACS module 5800 may be portable andconfigured to move within a workcell 5610 and cartridge 5620. Forexample, a robot may move the MACS module 5630 between differentinstruments of a workcell 5610.

FIGS. 59A and 59B are perspective views of a system 5900 for cellprocessing (e.g., CCE system) comprising a CCE module 5930 (e.g.,cartridge) including a housing 5931 and a rotor 5910, a CCE instrument5932, an optical sensor 5960, and an illumination source 5962. In somevariations, the CCE instrument 5932 may comprise a magnet configured tomagnetically rotate the rotor 5910 within the CCE module 5930. One ormore portions of the housing 5931 and rotor 5910 may be opticallytransparent to facilitate illumination by the illumination source 5962and image data generation by the optical sensor 5960.

In some variations, the system 5900 for cell processing may comprise acartridge 5930 comprising a housing 5931 comprising a rotor 5910configured to separate cells from a fluid. An instrument 5932 comprisinga magnet may be configured to interface with the cartridge 5930 tomagnetically rotate the rotor 5910. The cartridge 5930 may be configuredto move a cell product between a plurality of instruments. In somevariations, the housing 5931 may enclose the rotor 5910. In somevariations, the housing 5931 may comprise one or more apertures 5937configured to facilitate visualization (e.g., imaging) of the rotor5910. FIGS. 59A and 59B depict a magnet 5932 in proximity, but notattached, to housing 5931. FIG. 59C is a perspective view of the rotor5910 and housing 5931 without the magnet 5932, optical sensor 5960, andillumination source 5962.

In some variations, the cartridge 5930 (e.g., housing 5931, 5910) maycomprise a consumable component such as a disposable component, limiteduse component, single use component, and the like. In some variations,the magnet 5932 may comprise a durable component that may be re-used aplurality of times. In some variations, the magnet 5932 may bereleasably coupled to the housing 5931. For example, the housing 5931may be moved relative to the magnet 5932 to facilitate magnetic couplingbetween the magnet 5932 and a plurality of cartridges 5930. Additionallyor alternatively, the magnet 5932 may be configured to be moved relativeto the housing 5931.

FIG. 59D is a side cross-sectional view of a CCE module 5930. In somevariations, the housing 5931 of the rotor 5910 may comprise a first side5933 comprising the first fluid port 5912 (e.g., first fluid conduit)and a second side 5935 comprising the second fluid port 5914 where thesecond side 5935 is opposite the first side 5933. The rotor 5910(including a cone or bicone as described in more detail herein) may becoupled between the first fluid port 5912 and the second fluid port5914. In some variations, the CCE module 5930 may comprise an air gap5902 between the housing 5931 and a magnet 5932. That is, the cartridge5930 and magnet 5932 may couple in a non-contact manner. Consequently,the cartridge need not mechanically couple to the magnet 5932 to performcounterflow centrifugal elutriation. Therefore, the rotor 5910 may havea low alignment sensitivity with the magnet 5932, as well as lowvibration between the rotor 5910 and the magnet 5932. Furthermore, thespace between the rotor 5910 and magnet 5932 enables the second fluidport 5914 to extend toward the second side 5935 of the housing 5931,thus allowing for fluid to flow on each side of the rotor 5910.

In some variations, counterflow centrifugal elutriation may be performedby the system 5900 by moving a magnet 5932 towards a rotor 5910 (or viceversa). The rotor may define a rotational axis (e.g., coaxial with thefirst fluid port 5912 and the second fluid port 5914). Fluid may flowthrough the rotor via the first fluid port 5912 and the second fluidport 5914. The magnet 5932 may magnetically rotate the rotor about therotational axis while flowing the fluid through the rotor 5910. Therotor may move away from the magnet. For example, moving the rotor 5910may include advancing and withdrawing the rotor 5910 relative to themagnet 5932 using a robot (not shown).

In some variations, fluid may flow through first fluid port 5912 alongthe first side 5933 of the rotor 5910 and into the rotor 5910. Aftercounterflow centrifugal elutriation through the rotor 5910, the fluidmay flow out of the rotor 5910 through second fluid port 5914 along thesecond side 5935 of the rotor 5910.

In some variations, counterflow centrifugal elutriation may bevisualized by optical sensor 5960 and illumination source 5962 in orderto monitor and modify cell separation in real-time based onpredetermined criteria in a closed loop manner in order to maximizeelutriation efficiency. In some variations, an optical sensor 5960 maybe configured to image any portion of the rotor through which fluidflows (e.g., first fluid conduit, second fluid conduit, third fluidconduit, first bicone, second bicone). For example, image data of one ormore of the fluid and the cells in the rotor 5910 may be generated usingthe optical sensor 5960. In some variations, one or more of the fluidand the cells may be illuminated using the illumination source 5962. Forexample, an output of a cone may be imaged by an optical sensor toidentify non-target cells being elutriated.

In some variations, one or more of a rotation rate of the rotor and aflow rate of the fluid may be selected based at least in part on theimage data. For example, the rotor may comprise a rotation rate of up to6,000 RPM. For example, the fluid may comprise a flow rate of up toabout 150 ml/min while rotating the rotor. In some variations, the rotormay be moved towards the illumination source 5962 and the optical sensor5960. Additionally or alternatively, the rotor 5910 may be moved awayfrom the illumination source 5962 and the optical sensor 5960.

FIG. 59E is a side cross-sectional view of a rotor 5910 including afirst fluid port 5912 (e.g., fluid conduit, inlet) and a second fluidport 5914 (e.g., fluid conduit, outlet). In some variations, the firstfluid port 5912 and the second fluid port 5914 may extend in parallelwith each other and/or a rotational axis of the rotor 5910. In somevariations, the first fluid port 5912 and the second fluid port 5914 maybe disposed on opposite sides of the rotor 5910, which may simplifyfluid routing, cartridge design, and also reduce manufacturing costs.For example, the fluidic seals may be simplified since they contain onlya single lumen each. Conventionally, a complicated fluid flow path(including inlet and outlet) is formed on a first side of a rotor due toa fixed mechanical coupling of a drive motor to a second side of therotor. FIGS. 59F and 59G are cross-sectional side views of a rotor 5910disposed within housing 5931.

FIG. 60A is a plan view of a rotor 6000 that may be used with any of theCCE systems, CCE modules, cartridges, housings, combinations thereof,and the like described herein. The rotor 6000 may comprise a first fluidconduit 6010, a cone 6020 (e.g., bicone), a second fluid conduit 6030, amagnetic portion 6040 (e.g., magnet), and housing 6050. Fluid may flowsequentially through the first fluid conduit 6010, the cone 6020, andthe second fluid conduit 6030. In some variations, the magnetic portion6040 may comprise one or more magnets. In some variations, the rotor6000 may define a rotation axis 6060. In some variations, at least aportion of the first fluid conduit 6010 and at least a portion of thesecond fluid conduit 6030 may extend parallel to the rotation axis(e.g., into and out of the page with respect to FIG. 60A). In somevariations, at least a portion of the first fluid conduit 6010 and atleast a portion of the second fluid conduit 6030 may be co-axial.

In some variations, the cone 6020 may comprise a bicone having a firstcone including a first base and a second cone including a second basesuch that the first base faces the second base. In some variations, abicone may comprise a cylinder (or some other shape) between and/or influid communication with the first cone and the second cone. Forexample, one or more cones of a rotor may comprise a generally steppedshape. For example, one or more cones may comprise stacked circularsteps. In some variations, a cone of a rotor may comprise a single cone.

In some variations, at least a portion of the rotor may be opticallytransparent to facilitate visualization and/or imaging of the rotor 6000and/or fluid (e.g., cells) in the rotor 6000. For example, the cone 6020may be transparent, as well as portions of the first fluid conduit 6010and the second fluid conduit 6030.

In some variations, the cone may comprise a volume of between about 10ml and about 40 ml. In some variations, the cone may comprise a coneangle of between about 40 degrees and about 60 degrees.

In some variations, a cone may comprise a first cone (e.g., distal cone)and a second cone (e.g., proximal cone) where the first cone is largerthan the second cone. In some variations, a first cone length may bebetween about 60 mm and about 90 mm. In some variations, a proximal conelength may be between about 15 mm and about 40 mm. In some variations, acone diameter (e.g., maximum diameter of the cone) may be between about15 mm and about 40 mm.

In some variations, the rotor 6000 may comprise an asymmetric shape. Insome variations, a first portion (e.g., first end) of the rotor 6000 maycomprise the cone 6020 and a second portion (e.g., second end) maycomprise a paddle shape.

In some variations, the cone may comprise a length of at least about 4cm (e.g., between about 9 cm and about 12 cm), a cone diameter of about5 cm or less (e.g., between about 3 cm and about 5 cm), a fluid flowrate of up to about 100 ml/min (e.g., between about 60 ml/min and about100 ml/min), and a rotation rate of less than about 3000 RPM. The shapeof the first cone and the second cone may be generally linear (asopposed to convex or concave).

FIGS. 60B and 60C are perspective views, and FIG. 60D is a side view ofa rotor 6002 comprising a first fluid conduit 6012, a cone 6022, asecond fluid conduit 6032, and a housing 6052. FIG. 60E is a perspectiveview of the rotor 6002 disposed in a housing 6090.

FIG. 60F is a plan view of a rotor 6004 having two cones (e.g., twobicones) configured to elutriate cells (e.g., red blood cells,leukapheresis product) in a second cone in order to recirculate a bufferfor reuse. The rotor 6004 may comprise a housing 6052, a first fluidconduit 6012, a first cone 6022 coupled to the first fluid conduit 6012,a second fluid conduit 6023 coupled to the first cone 6022, and a secondcone 6024 coupled to the second conduit 6023, and a third fluid conduit6032 coupled to the second cone 6024. The first cone 6022 may comprise afirst volume, and the second cone 6024 may comprise a second volumelarger than the first volume. In some variations, a ratio of a secondvolume to a first volume may be between about 2:1 to about 5:1. Fluidmay flow sequentially through the first fluid conduit 6012, the firstcone 6022, the second fluid conduit 6023, the second cone 6024, and thethird fluid conduit 6032. In some variations, the rotor 6004 maycomprise a magnetic portion 6042.

In some variations, the first cone 6022 may comprise a first bicone andthe second cone 6024 may comprise a second bicone. In some variations,the first bicone may comprise a third cone including a first base and afourth cone including a second base such that the first base faces thesecond base. In some variations, the second bicone may comprise a fifthcone including a third base and a sixth cone including a fourth basesuch that the third base faces the fourth base.

In some variations, a portion of the rotor 6004 may be opticallytransparent, such as first cone 6022, second cone 6024, and at least aportion of first fluid conduit 6012, second fluid conduit 6023, andthird fluid conduit 6032. In some variations, the first fluid conduit6012 may comprise an inlet and the third fluid conduit 6032 may comprisean outlet.

In some variations, cells may enter the first cone 6022 and red bloodcells (RBCs) 6030 may be elutriated into the second cone 6024. Since thesecond cone 6024 is further out from an axis of rotation (center ofhousing 6052), the RBCs 6030 may be concentrated at an inlet 6025 of thesecond cone 6024 due to centrifugation. The larger volume of the secondcone 6024 may further reduce the velocity of fluid (e.g., buffer),thereby reducing the force on RBCs 6030 within the second cone 6024. Byrecirculating the fluid (e.g., buffer), a higher concentration of RBCsmay be elutriated with less fluid (e.g., buffer). In some variations,white blood cells 6040 may be harvested from the first cone 6022. Anoptical sensor may be configured to image the first cone 6022 togenerate imaging data used to identify a boundary between the WBCs 6040and RBCs 6030. In some variations, the recirculating fluid may be passedthrough a filter to remove small particles (e.g., platelets) with lessfluid (e.g., buffer).

FIG. 60G is a plan view and FIG. 60H is a side view of a rotor 6005having two cones (e.g., two bicones) configured to elutriate cells(e.g., red blood cells) in a second cone. A rotor having two cones mayfacilitate recirculation of buffer for reuse. The rotor 6006 maycomprise a housing 6052, a first fluid conduit 6012, a first cone 6022coupled to the first fluid conduit 6012, a second cone 6024 coupled tothe first cone 6022, and a fluid conduit 6032 (e.g., outlet) coupled tothe second cone 6024.

FIGS. 11A-11C depict another variation of the counterflow centrifugalelutriation (CCE) module 1100. FIG. 11A is a perspective view of acartridge 1110 comprising a CCE module 1100 in an extended configurationconfigured to receive a CCE instrument. FIGS. 11B and 11C arecross-sectional side views of a CCE module 1100 in respective retractedand extended configurations. In some variations, a CCE module maycomprise a conical element having an internal surface and an externalsurface fixedly attached to a distal end of a linear member having aninternal surface and an external surface. The proximal end of the linearmember may be rotationally attached to a fulcrum in order to enableextension, retraction, and/or rotation of the linear member. Forexample, FIG. 11C depicts a linear member extended outside the housingof the cartridge and then rotated to generate a centrifugal force. Acell product may be conveyed between the internal surface and externalsurface of the linear member (optionally in tubing) to the conicalelement and fed into an opening at the distal end of the internalsurface of the conical element, such that the flow of the cell productmay run counter to the centrifugal force generated by rotation of thelinear member. Cells in the cell product may be separated based on theratio of their hydrodynamic cross section to their mass, due to thecounterflow of the solution and sedimentation of cells subject tocentrifugal force. The flow rate may then be increased and/or therotation of the linear member may be decreased to permit cells toselectively return through the void in the interior surface of thelinear member to the proximal end of the linear member. The selectedcells may be directed into a tube that returns the selected cells to thecartridge. After an enrichment/washing step is performed, the linearmember may be retracted into the housing to the retracted configurationas shown in FIG. 11B.

Magnetic Cell Selection

Generally, the systems and methods described herein may select cells onthe basis of magnetically labeled cells corresponding to cells having apredetermined antigen. For example, a cell suspension of interest may beimmunologically labeled with magnetic particles (e.g., magnetic beads)configured to selectively bind to the surface of the cells of interest.The labeled cells may generate a large magnetic moment when the cellsuspension is flowed through a flow cell. The flow cell may be disposedin proximity to a magnet array (e.g., permanent magnets, electromagnet)generating a magnetic field having a gradient across the flow cell toattract the labeled cells for separation, capture, recovery, and/orpurification. The magnet array may be configured to generate non-uniformmagnetic fields at the edges and the interfaces of the individualmagnets so as to cover the full volume of the flow cell such that amagnetophoretic force equals a drag force exerted by the fluid flowingthrough the flow cell.

FIG. 61A-61C are schematic views of a magnetic cell separation (e.g.,magnetic-activated cell selection) system and process. A magnetic cellseparation system may comprise a flow cell 6110 comprising an inlet 6130and an outlet 6132, a magnet array 6120, a first fluid source 6140(e.g., input sample source), a second fluid source 6142 (e.g., buffersource), a third fluid source 6150 (e.g., target cell reservoir), afourth fluid source 6152 (e.g., waste reservoir), and a set of valves6134. As shown in step 6100, a set of cells 6160, 6170 may compriselabeled cells 6160 (e.g., magnetically labeled cells) and non-labeledcells 6170 may flow into the flow cell 6110. For example, a set of thecells 6160 may be labeled with a magnetic-activated cell selection(MACS) reagent. A MACS reagent may be incubated with the set of cells tolabel (e.g., attach, couple) the cells to the MACS reagent. As describedin more detail herein, the magnet array 6120 may be disposed external tothe flow cell 6110 such that the magnet array 6120 may be moveablerelative to the flow cell 6110. For example, the magnet array 6120 maymove away from the flow cell 6110 to facilitate flowing the set of cells6160 out of the flow cell 6110. Conventional flow cells comprisetortuous paths including meshes and/or beads to capture cells. However,recovery of labeled cells from conventional flow cell configurations isdifficult, By contrast, the flow cells 6110 described herein may lacktortuous paths such as beads, meshes, and the like, and therefore enableserial separations to be performed efficiently using either positiveselection or negative selection. In some variations, the flow cells maycomprise generally laminar channels as described in more detail herein.

At step 6102, the magnet array 6120 may magnetically attract the set ofcells 6160 towards the magnet array 6120 for a predetermined dwell timeand/or based on a measured quantity of magnetically separated cells. Insome variations, the dwell time may be at least one minute (e.g., atleast two minutes, at least three minutes, at least five minutes). Thenon-labeled cells 6170 are not magnetically attracted to the magnetarray 6120 and may flow out of the outlet 6132 of the flow cell 6110 andinto the fourth fluid source 6152. In some variations, the fluid (e.g.,cells 6160, 6170) within the flow cell may be held statically within theflow cell 6110 for a dwell time before the fluid (e.g., cells 6170) flowfrom outlet 6132. In some variations, a longitudinal axis of the flowcell 6110 may be oriented substantially perpendicular to ground in orderfor fluid flow through the flow cell 6110 to be aided by gravity. Atstep 6104, the magnetic coupling between the magnet array 6120 and thecells 6160 may be released after the dwell time, and the cells 6160 mayflow into the third reservoir 6150.

In some variations, stiction may cause cells to remain attached to asurface of a flow cell even after removal of a magnet array 6120.Therefore, a gas may be flowed through the flow cell 6110 to aid cellcollection into the third reservoir 6150. Gas flow through the flow cellmay provide improved cell recovery over liquid flushing through the flowcell. An interface generated by a gas (e.g., bubble, air gap) may bemaintained by gravity, thereby enabling implementation of a relativelywide flowcell that further improves cell recovery relative to ahorizontally oriented flow cell. The MACS modules described herein maybe configured for positive selection and/or negative selection bymodifying the sequence of steps.

Additionally or alternatively, an optical sensor may be configured toimage a flow cell to generate imaging data used to identify a quantityof cells magnetically attracted to the magnet array. Fluid containinglabeled cells may be flowed out of the flow cell when a predeterminedquantity of cells have been measured by the optical sensor.

FIG. 62A is a perspective view of a MACS module 6200 in a firstconfiguration. The MACS module 6200 (as well as any of the MACS modulesdescribed herein) may be a component of any of the cartridges describedherein. For example, a cartridge for cell processing may comprise aliquid transfer bus and a plurality of modules with each modulefluidically linked to the liquid transfer bus. The MACS module 6200 maycomprise a flow cell 6210 comprising an elongate cavity having a cavityheight, an inlet 6230, and an outlet 6232. The MACS module 6200 mayfurther comprise a magnet array 6220 comprising a plurality of magnets.Each of the magnets may be spaced apart by a spacing distance, such asillustrated in FIGS. 62G, 63D, and 63E, although FIGS. 62A-62Eillustrate a magnet array 6220 with magnets in contact with adjacentmagnets.

FIG. 62G is a schematic diagram of the flow cell 6210 and magnet array6220. In some variations, the flow cell 6210 may comprise a cavityheight 6202 and a cavity width 6204. Fluid may be configured to flowthrough the flow cell 6210 in a first direction 6206. The magnet array6220 may comprise a plurality of magnets with each magnet comprising arespective width 6222. In some variations, adjacent magnets may beseparated by a predetermined spacing distance 6224. Each magnet pair mayhave the same or different spacing distance 6224. As shown in FIG. 62G,an orientation (e.g., poles) of the magnets in the magnet array 6220 maycomprise a predetermined pattern.

In some variations, a ratio of the cavity height 6202 to the spacingdistance 6224 is between about 20:1 and about 1:20, between about 10:1and about 1:10, between about 5:1 and about 1:5, and between about 3:1and about 1:3, including all values and sub-ranges in-between. In somevariations, an actuator 6240 (e.g., linear, rotary) may be configured tomove the magnet array 6220 relative to the flow cell 6210. In somevariations, an orientation (e.g., poles) of the magnets in the magnetarray 6220 may comprise a predetermined pattern (e.g., Halbach array).

In some variations, the magnet array 6220 may move relative to the flowcell 6210 or vice versa. FIG. 62A illustrates the MACS module 6200 in anopen configuration and FIG. 62B illustrates the MACS module 6200 in aclosed configuration. FIG. 62B is a perspective view of the MACS system6200 in a second configuration where labeled cells may be magneticallyattracted towards the magnet array 6220. In the second configuration,the magnetic field lines generated by the magnet array traverse the flowchannel exerting a magnetophoretic force on magnetically tagged cellsthat are injected into the channel. FIG. 62C is a cross-sectional sideview of the MACS system 6200 including the magnet array 6220. FIG. 62Dis a perspective view of a MACS system 6200 in the second configuration.FIG. 62E is a plan view of a flow cell 6210 and magnet array 6220 of aMACS system. FIG. 62F is a plan view of a flow cell 6210 of a MACSsystem.

FIG. 63A-63E are perspective views of a set of magnet arrays 6300, 6310,6320, 6330, 6340. One or more of the size, strength, shape, spacing, andorientation of the magnets in a magnet array may be set to generate amagnetic field to attract magnetically-labeled cells. Additionally oralternatively, a magnet array may comprise a high-magnetic permeabilitymaterial configured to enhance or reduce the field strength and fieldgradients within the flow cell. The material may be disposed between amagnet and flowcell. Additionally or alternatively, the material may bedisposed within the flowcell and/or on one or more sides of theflowcell.

FIGS. 64A and 64B are respective perspective and cross-sectional sideviews of a MACS module 6400 comprising a flow cell 6410 and a magnetarray 6420. The flow cell 6410 may comprise a set of linear channels6412, 6414, 6416 comprising a first channel 6412 parallel to a secondchannel 6414, and a third channel 6416 in fluid communication with eachof the first channel 6412 and the second channel 6416. As shown in FIG.64B, the third channel 6416 may be disposed between the first channel6412 and the second channel 6416 and define a volume where fluid fromthe first channel 6412 and the second channel 6416 interact (e.g., mix).In some variations, the flow cell 6410 may comprise a first inlet 6430coupled to the first channel 6412 and configured to receive a firstfluid 6460 (e.g., cells). A second inlet 6431 may be coupled to thesecond channel 6414 and configured to receive a second fluid 6470 (e.g.,buffer). The flow cell 6410 may comprise a first outlet 6432 coupled tothe first channel 6412 and a second outlet 6433 coupled to the secondchannel 6414.

The magnet array 6420 may be disposed external to the flow cell 6400 andmay be moved relative to the flow cell 6400 as described herein. In somevariations, a longitudinal axis of the flow cell 6410 may beperpendicular to ground such that fluid flows in a generally verticaldirection.

In some variations, the first channel 6412 may have different dimensionsform the second channel 6414. For example, a first cavity height of thefirst channel 6412 may be larger than a second cavity height of thesecond channel 6414. For example, a ratio of the first cavity height toa second cavity height may be between about 1:1 to about 3:7, betweenabout 1:1 to about 2:3, and between about 2:3 to about 3:7, includingall values and sub-ranges in-between. Fluid flowing through the firstchannel 6412 may have a slower flow rate relative to the second channel6414 due to the larger cavity height of the first channel 6412 relativeto the second channel 6414. In some variations, the third channel 6416may comprise a ratio of a length of the third channel 6416 to a diameterof the third channel 6416 of between about 2:1 to about 6:1, betweenabout 2:1 to about 3:1, between about 3:1 to about 4:1, between about4:1 to about 5:1, between about 5:1 to about 6:1, and between about 3:1to about 5:1, including all values and sub-ranges in-between.

As shown in FIG. 64B, a first fluid 6462 may flow through the flow cell6410 generally following a first direction. The magnetically-labeledcells 6416 within the first fluid 6462 may separate from the rest of thefirst fluid 6462 within the third channel 6416 as the magneticattractive forces generated by magnet array 6420 pulls the cells 6416away from the first channel 6412 and towards the second channel 6414(e.g., towards the magnet array 6420). Similarly, a second fluid 6470(e.g., buffer) may flow through the second channel 6414. As the cells6416 flow towards the magnet array 6420, they displace the second fluid6470 flowing through the third channel 6416 such that a portion of thesecond fluid 6470 may flow into the first channel 6412. In this manner,magnetically-labeled cells 6416 may be magnetically separated from afirst fluid 6462 and the second fluid 6470 may aid removal of the firstfluid 642 not including the cells 6416.

In some variations, a set of fluidic loops may be coupled to the flowcell to enable a plurality of cell separation cycles. FIG. 64C is aschematic diagram of a MACS module comprising a flow cell 6410, a firstfluid conduit 6480 coupled to an inlet 6430 of the flow cell 6410 and anoutlet 6432 of the flow cell 6410. The first fluid conduit may 6480 maybe configured to receive the set of cells from an outlet 6432 of theflow cell 6410 for recovery and/or recirculation through the inlet 6430of the flow cell 6410. A second fluid conduit 6490 may be coupled to theinlet 6431 of the flow cell 6410 and the outlet 6433 of the flow cell6410 to recirculate fluid such as buffer and unrecoveredmagnetically-labeled cells. The second fluid conduit 6490 may beconfigured to receive a fluid without the set of cells from the flowcell 6410. Higher purities of labeled cells may be recovered based on anumber of cycles performed. For example, a single cell separation cyclemay yield about 80% cell purity, a second cell separation cycle mayyield about 96% cell purity, a third cell separation cycle may yieldabout 99.2% cell purity, and a fourth cell separation cycle may yieldabout 99.84% cell purity.

In some variations, applying a centrifugal force to a magnetic cellseparation process may further attract labeled cells toward a magneticarray independently of fluid flow rate so as to maintain throughput.FIGS. 65A-65C are schematic diagrams of a MACS module 6500 utilizingcentrifugal force to aid a cell separation process. FIG. 65A depicts aflattened flow cell 6510 configured to be wrapped to form a generallycylindrical shape 6512. The flow cell 6510 may comprise a curved flowpath 6520.

FIG. 65B illustrates a cylindrical flow cell 6510 concentricallysurrounded by (e.g., nested within) a cylindrical magnet array 6530. InFIG. 65B, only a cross-section of the magnet array 6530 is shown for thesake of clarity. The flow cell 6510 may be spaced apart from the magnetarray 6530 by a predetermined spacing distance. Accordingly, the flowcell 6510 may be configured to rotate 6550 about a longitudinal axis togenerate a centrifugal force on the fluid 6540 within the flow path 6520in an outward direction towards the magnet array 6530. During a cellseparation process, the fluid may be subject to set of forces depictedin FIG. 65C including a bulk fluidic force 6560 in an axial (e.g., bulkflow) direction, a centrifugal force 6570 in a radially outwarddirection from a center of rotation (e.g., proportional to a netparticle system buoyancy), and a magnetic force 6580 extending radiallyoutward from a center of rotation (e.g., proportional to net particlesystem magnetic attractiveness). In some variations, labeled cells maycomprise a higher density than non-labeled cells. Therefore, centrifugalforce may preferentially push the labeled cells towards the magnet 6530,further increasing the specificity and efficiency of cell separation.

FIGS. 66A-66C are schematic diagrams of a cell separation system andprocess. A magnetic cell separation system may comprise a flow cell 6610comprising a flow path 6620 (shown schematically flattened for sake ofclarity), and a magnet array 6630. As shown in step 6600, a set of cells6640, 6642 may comprise labeled cells 6640 (e.g., magnetically labeledcells) and non-labeled cells 6642 may flow into the flow path 6620 offlow cell 6610. For example, a set of the cells 6640 may be labeled witha magnetic-activated cell selection (MACS) reagent. The magnet array6630 may be disposed external to the flow cell 6610 such that the magnetarray 6630 may be moveable relative to the flow cell 6610. For example,the magnet array 6630 may move away from the flow cell 6610 tofacilitate flowing the set of cells 6640 out of the flow cell 6610.

At step 6602, the flow cell 6650 may be rotated to generate centrifugalforce to push the cells 6640, 6642 toward the magnet array 6630. In somevariations, a longitudinal axis of the flow cell 6610 may be orientedsubstantially perpendicular to ground in order for fluid flow throughthe flow cell 6610 to be aided by gravity. At step 6604, the magnetarray 6630 may magnetically attract the set of cells 6640 towards themagnet array 6630 for a predetermined dwell time as described herein.The non-labeled cells 6642 are not magnetically attracted to the magnetarray 6630 and may flow out of the flow cell 6610 into, for example, awaste vessel. In some variations, the fluid (e.g., cells 6160, 6170)within the flow cell may be held statically within the flow cell 6110for a dwell time before the fluid (e.g., cells 6170) flow from outlet6132. In some variations, the magnetic coupling between the magnet array6630 and the cells 6640 may be released after the dwell time, and thecells 6640 may be recovered.

FIGS. 12A and 12B illustrate the magnet of the MACS instrument 1200comprising a magnet and a MACS module 1210. The magnet is shown in FIG.12A in an ON configuration and shown in FIG. 12B in an OFFconfiguration.

Bioreactor

The bioreactors described herein may comprise a vessel configured toculture mammalian cells. Generally, cell and gene therapy products maybe grown in a bioreactor to produce a clinical dose which maysubsequently be administered to a patient. A number of biological andenvironmental factors may be controlled to optimize the proliferationspeed and success of cell growth. The bioreactor modules describedherein enable one or more of monitoring, adjusting, and/or controllingof cell growth (e.g., to facilitate consistent and efficient cellularproliferation).

FIG. 67A is a schematic diagram of a cell processing system 6700 (e.g.,bioreactor module) comprising one or more of a bioreactor 6710, one ormore sensors 6720, an agitator 6730, a temperature regulator 6740, and agas regulator 6750. In some variations, the sensor 6720 may beconfigured to monitor (e.g., measure, sense, determine) one or morecharacteristics of the bioreactor module 6700 and cells in thebioreactor 6710. For example, the sensor 6720 may comprise one or moreof a pH sensor, a dissolved oxygen (DO) sensor, a temperature sensor, aglucose sensor, a lactose sensor, a cell density sensor, a humiditysensor, combinations thereof, and the like. One or more of the sensorsmay be a non-invasive optical sensor.

FIGS. 67B-67D are schematic diagrams of a cell processing systemcomprising a workcell 6760, a bioreactor system 6700 (e.g., bioreactorinstrument), a cartridge 6770, an agitator 6730, and a fluid connector6780. In some variations, a cartridge 6770 for cell processing maycomprise a liquid transfer bus and a plurality of modules (e.g.,bioreactor module, CCE module, MACS module, EP module). Each module maybe fluidically linked to the liquid transfer bus. The bioreactor modulemay comprise at least one bioreactor.

The bioreactor instrument 6700 may be configured to interface with thecartridge 6770. In some variations, the bioreactor instrument 6700 maycomprise the agitator 6730 configured to couple to the bioreactor. Theagitator may be configured to agitate cell culture media comprisingcells. In some variations, the fluid connector 6780 may be configured tocouple the bioreactor system 6700 and workcell 6760.

FIG. 67B depicts a cartridge 6770 comprising a bioreactor disposedwithin a workcell 6760. The bioreactor 6700 may be uncoupled from theworkcell 6760. Once the fluid connector 6780 couples (e.g., to create asterile flow path) the workcell 6760 to the bioreactor 6700, thecartridge 6770 may be moved into the bioreactor 6700, as shown in FIG.67C. For example, the cartridge 6770 may be coupled to (e.g., disposedon) an agitator 6730 and then agitated, as shown in FIG. 67D. In somevariations, the fluid connector 6780 may comprise a set of foldablesidewalls (e.g., like an accordion) configured to receive and dissipatethe agitation of the agitator 6730 without transmitting such motion tothe workcell 6760. That is, the fluid connector 6780 may function as abellows to maintain the connection between the workcell 6760 andbioreactor 6700 without agitating the workcell 6760. In some variations,the fluid connector 6780 may couple the bioreactor (e.g., of cartridge6770) to a liquid transfer bus.

In some variations, an agitator may be configured to generate motion(e.g., orbital, rotary, linear) to the bioreactor in order to mix theculture in instances where it is required to encourage interactions witha reagent and cells. For example, orbital motion may be used to create ahomogenous culture volume such that a small sample taken from theculture may be representative of the culture at large. In somevariations, the agitator 6730 may comprise one or more impellers. Theagitator 6730 may be configured to provide variable-intensity mixingduring culture at defined periods.

In some variations, orbital motion may encourage increased interactionswithin the cell culture, such as in the toroidal bioreactors describedherein that comprise a geometry that may encourage the continuous andgentle flow of fluid around the bioreactor, thereby aiding homogenousmixing with minimal shear stress transferred to the cells.

In some variations, the temperature regulator 6740 may be configured tocontrol a temperature of a bioreactor and corresponding processes. Thetemperature regulator 6740 may be coupled to the bioreactor. Forexample, the temperature regulator 6740 may control a temperature of acell culture to be between about 2° C. and about 40° C. and therebyensure that a culture is heated to physiological conditions and cooledto slow metabolic processes (e.g., to keep cells in a dormant state) asdesired. For example, the thermal regulator 6740 may comprise acirculating coolant coupled to a heat exchanger coupled to a thermalinterface (e.g., heating/cooling plate).

In some variations, the gas regulator 6750 may be coupled to thebioreactor and configured to control a gas composition of a bioreactorand corresponding processes using one or more of Clean Dry Air (CDA),carbon dioxide, and nitrogen. The gas regulator 6750 may be coupled tothe bioreactor. For example, the sensors 6720 and gas regulator 6750 mayprovide closed-loop gas control of the bioreactor module 6700. In somevariations, CDA may comprise oxygen such as pure oxygen. In somevariations, the gas regulator may comprise a manifold coupled to one ormore gas sources. The manifold may include a solenoid coupled to a valve(e.g., restrictive orifice) configured to control gas flow through thebioreactor 6710. The solenoid may be configured to pulse to control aquantity and composition of gas received through the manifold.Additionally or alternatively, one or more of a proportional valve andMass Flow Controller (MFC) may be configured to meter and control theflow of gas to a manifold. In some variations, the gas regulator 6750may comprise one or more sensors to measure the gas mixture and/or flowrate. Additionally or alternatively, the sensors may be configured forclosed-loop control of gas flow through the gas regulator.

In some variations, measured pH from a pH sensor may be used to controla pH of the bioreactor 6710 using the gas regulator 6750. For example,in response to the measured pH, gas regulator 6750 may control a CO₂concentration of the gas contacting the cell culture to control the freehydrogen ions and pH of the culture. In some variations, a pH of thebioreactor 6710 may be between about 5.5 and about 8.5. One or more ofCO₂ composition of the gas in the bioreactor 6710, buffer, and reagents(e.g., acid, base) may be used to regulate pH. In some variations, adissolved oxygen concentration of the bioreactor 6710 may be betweenabout 0% and about 21%. Nitrogen composition of the gas in thebioreactor 6710 may be used to regulate the dissolved oxygenconcentration. For example, control of both the agitator in thebioreactor and the flow rate and composition of the gas contacting thecell culture may regulate the dissolved carbon dioxide concentration.

In some variations, measured dissolved oxygen from a dissolved oxygensensor may be used to control an oxygen concentration (e.g., belowatmospheric levels) of the bioreactor 6710 using the gas regulator 6750.For example, gas regulator 6750 may control a nitrogen concentration ofthe gas contacting the cell culture to create hypoxic conditions.

FIGS. 68A and 68B are cross-sectional perspective views of a bioreactor6800 comprising an enclosure 6810 comprising a base 6812, a sidewall6814, and a top 6816. A gas-permeable membrane 6820 may be coupled toone or more of the base 6812 and the sidewall 6814 of the enclosure6810. In some variations, the enclosure 6810 may comprise a firstchamber 6830 having a first volume and a second chamber 6832 having asecond volume, the first chamber 6830 separated from the second chamber6832, and the first volume smaller than the second volume. In somevariations, the first chamber 6830 may be concentrically nested withinthe second chamber 6832. For example, nesting the chambers may enablelarger overall working volume ranges (e.g., 100:1). The first chamber6830 may comprise a well shape with an angled base surface to promotefluid pooling at a center of the first chamber 6830 during aspiration.In some variations, the base 6812 may be disposed on a thermal regulator(not shown) such as a thermoelectric element. In some variations, theenclosure 6810 may be composed of a thermally conductive material suchas a metal (e.g., aluminum).

In some variations, the bioreactor 6800 may be coupled to a gasregulator (not shown) to facilitate gas transfer through thegas-permeable membrane 6820 (e.g., into and out of the culture). Thegas-permeable membrane 6820 may be configured to hold a cell culture.Gas may diffuse through the surfaces of the culture that contact thegas-permeable membrane to enable increased oxygenation of the cellculture and removal of gaseous metabolic byproducts of the cell culture,and thus increase the potential for metabolic activity. For example, thegas-permeable membrane 6820 enables dissolved oxygen to diffuse into theculture in close proximity to a cell bed where the oxygen may beconsumed. In some variations, the bioreactor may be coupled to both afirst gas regulator to facilitate gas transfer through the gas-permeablemembrane and a second gas regulator to facilitate control of headspacegas composition.

In addition to gas transfer, the bioreactors described herein may beconfigured to efficiently control a temperature of a cell culture usinga conductive thermal interface (e.g., gas-permeable membrane 6820,enclosure 6810) along both a base and sidewall of the bioreactor.

In some variations, the first chamber 6830 may comprise a working volumeof between about 10 ml and about 100 ml. In some variations, the firstchamber 6830 may comprise a total volume of between about 10 ml andabout 130 ml. In some variations, the second chamber 6832 may comprise aworking volume of between about 100 ml and about 1000 ml. In somevariations, the second chamber 6832 may comprise a total volume ofbetween about 100 ml and about 1400 ml. In some variations, the firstchamber 6830 may comprise a diameter of between about 10 mm and about100 mm, and a height of between about 10 mm and about 100 mm. In somevariations, the second chamber 6832 may comprise a diameter of betweenabout 100 mm and about 250 mm, and a height of between about 10 mm andabout 100 mm.

As shown in FIG. 68B, a base 6822 of the gas-permeable membrane 6820 maycomprise an angle between about 3 degrees and about 10 degrees relativeto the base 6812 of the enclosure 6810. Similarly, FIGS. 69A and 69Bdepict a sloped base. For example, due to a slope of the base 6822, thechambers 6830, 6832 are deeper towards a center of the bioreactor 6800.This may encourage cell growth towards a center of the bioreactor 6800,which may aid one or more of cell sampling, cell transfer, cellrecovery, and the like. In some variations, orbital motion of thebioreactor 6800 may promote cell congregation toward a center of thebioreactor 6800, thereby increasing interaction between the cells.

In some variations, the gas-permeable membrane 680 may comprise a curvedsurface. In some variations, the gas-permeable membrane may comprise aset of patterned curved surfaces. For example, the set of patternedcurved surfaces may comprise a radius of curvature of between about 50mm and about 500 mm.

In some variations, the bioreactor may be configured to facilitatemonitoring (e.g., temperature, pH, dissolved oxygen) and fluid flow(e.g., gas composition, fluid transfer) between the chambers. As shownin FIG. 68C, the enclosure 6810 may comprise one or more nested surfacescurved around a longitudinal axis (e.g., center) of the enclosure 6810.For example, the nested surfaces may comprise a set of concentrictoroids. The enclosure 6810 may comprise a toroid shape. FIG. 68C is aperspective view and FIG. 68D is a bottom view of enclosure 6810comprising a set of apertures 6818 (e.g., holes, openings, slits,slots). In some variations, the apertures 6818 may enable gas and/orheat transfer between the components and chambers of the bioreactor6800. Additionally or alternatively, one or more sensors may be coupledto the apertures 6818. For example, the apertures 6818 may be coupled toa non-contact sensor (e.g., pH, DO) such as an optical sensor (notshown) configured to determine a fluorescent spot disposed on a surfaceof the bioreactor. In some variations, one or more of a sensor and fluidconnector may be introduced through the apertures 6818.

In some variations, the gas-permeable membrane extends along the base6812 and the sidewall 6814 of the enclosure 6810, as shown in FIG. 68B.In some variations, the gas-permeable membrane extends only along thebase 6812 of the enclosure 6810. FIG. 68E is a perspective view and FIG.68F is a side view of the gas-permeable membrane 6820 where an outersurface of the gas-permeable membrane 6820 comprises one or moreprojections 6824 (e.g., projections, spacers, ribs). The projections6824 are also depicted in the perspective view of FIG. 68G and bottomview of FIG. 68H. The projections 6824 contact the enclosure 6810 anddefine a cavity between the enclosure 6810 and the gas-permeablemembrane 6820. That is, the projections 6824 may be configured tomechanically space away the enclosure 6810 from a portion of thegas-permeable membrane 6820 to facilitate thermal transfer from theenclosure 6810 to the cell culture. In some variations the gas-permeablemembrane may comprise polydimethylsiloxane (PDMS) (e.g., silicone),fluorinated ethylene propylene (FEP), polyolefin (PO), polystyrene (PS),ethyl vinyl acetate (EVA) and have a thickness of between about 0.1 mmand about 0.4 mm, between about 0.2 mm and about 0.3 mm, and about 0.25mm, including all ranges and sub-values in-between.

FIG. 69A is a cross-sectional side view of an enclosure 6910 of abioreactor comprising a first chamber 6912, a second chamber 6914, and acolumn 6916 extending along a longitudinal axis of the enclosure 6910.FIG. 69B is a cross-sectional perspective view of the enclosure 6910showing the nested curves of the enclosure 6910. The column 6916 may beconfigured to promote cell culture in combination with agitation such asorbital motion.

FIG. 70 is an exploded perspective view of a bioreactor 7000 comprisingan enclosure 7010, a gas-permeable membrane 7020, and a top 7030. Thetop 7030 may be composed of a material such as polyethylene.

FIGS. 13A and 13B are perspective views of a cartridge 1300 andbioreactor instrument interface 1310. The bioreactor instrumentinterface 1310 is coupled to the cartridge 1300 in FIG. 13B.

FIG. 14 is a perspective view of a bioreactor instrument 1410 comprisinga set of cartridges 1400, 1402, 1404 and cavities 1420, 1422, 1424configured to receive a respective cartridge. In some variations, eachcartridge may be docked to enable simultaneous expansion, culturing, orresting steps.

Electroporation Module

In some variations, an electroporation module may be configured tofacilitate intracellular delivery of macromolecules (i.e., transfectionby electroporation). An electroporation module may contain a continuousflow or batch mode chamber and one or more sets of electrodes forapplying direct or alternating current to the chamber. An electricaldischarge from one or more capacitors, or current sources, may generatesufficient current in the chamber to promote transfer of apolynucleotide, protein, nucleoprotein complex, or other macromoleculeinto the cells in the cell product. As with other modules describedherein, one or more components used for the process step (here,electroporation) may be provided on the cartridge or in the instrumentto which the cartridge interfaces. For example, the capacitor(s) and/orbatteries may be provided in the module on the cartridge or in theinstrument. The electroporation module may, in some variations, beconfigured to apply an electric field to a cell suspension undercontinuous flow in a microfluidic device, e.g., as described in Garciaet al. Sci. Rep. 6:21238 (2016).

Additionally or alternatively, intracellular delivery of macromoleculesmay also be achieved by other methods, such as mechanoporation. Itshould be understood that throughout the disclosure variationscomprising an electroporation module may instead or in addition comprisea mechanoporation module, or another module configured to perform anysuitable method of delivering macromolecules into cells. Mechanoporationcan be achieved by, for example, applying transient, fluidic pressure toa solution containing cells, or by applying physical pressure to thecells (e.g., by microneedles). Illustrative methods of mechanoporationby passing a cell suspension through a constriction are provided, e.g.,in International Patent Publication No. WO 2017/041051 and WO2017/123663, and are incorporated by reference herein. Mechanoporationcan also be achieved by applying a vortex to a cell suspension in amicrofluidic device.

FIG. 72 is a schematic diagram of an electroporation module 7200 (e.g.,electroporation system) comprising an electroporation chamber 7210(which may comprise a fluid conduit), a pump 7220, an inlet 7230, anoutlet 7232, a set of pinch valves 7234, a first fluid source 7240(e.g., fluid reservoir, cell reservoir), a second fluid source 7242(e.g., vent, gas source), a set of sensors 7250 (e.g., bubble sensors),and a controller (e.g., processor and memory) configured to control themodule 7200, and a signal generator 7270 configured to deliver anelectroporation signal (e.g., voltage pulse) to the electroporationchamber 7210.

In some variations, the fluid conduit 7210 may be configured to receivea first fluid comprising cells and a second fluid. A set of electrodesmay be coupled to the fluid conduit 7210. A pump may be coupled to thefluid conduit 7210. The controller 7260 may be configured to generate afirst signal to introduce the first fluid into the fluid conduit 7210using the pump 7220, generate a second signal to introduce the secondfluid into the fluid conduit 7210 such that the second fluid separatesthe first fluid from a third fluid, and generate an electroporationsignal to electroporate the cells in the fluid conduit 7210 using theset of electrodes.

In some variations, the second fluid may comprise a gas or oil. In somevariations, the controller may be configured to generate a third signalto introduce the third fluid into the fluid conduit 7210. The thirdfluid may be separated from the first fluid by the second fluid. In somevariations, a cartridge for cell processing may comprise a liquidtransfer bus and a plurality of modules such as the electroporationmodule 7200. Each module may be fluidically linked to the liquidtransfer bus.

The set of sensors 7250 may be configured to measure fluid changes in afluid conduit such as a change from a first fluid to a second fluid(e.g., liquid to air) in the fluid conduit. The module 7200 may furthercomprise a set of valves configured to ensure fluid does not backflowinto the electroporation chamber 7210 and/or fluid source 7240. Theelectroporation chamber 7210 may comprise a cavity configured to hold afluid to be electroporated and a set of electrodes to apply anelectroporation signal to the fluid. For example, the signal generator7270 may generate a square valve pulse as described in more detailherein.

In some variations, the electroporation module 7200 (e.g., valves 7234,pump 7220, sensors 7250, and controller 7260) may be configured tocontrol fluid flow through the electroporation chamber 7210 in adiscontinuous (e.g., batch process) manner. For example, a first batchof cells may undergo electroporation and be physically separated from asecond batch of cells by an intermediate fluid such as air or fluid suchas oil. Separating cell batches may reduce mixing of transfected andnon-transfected cells, and further ensure fixed batch volume. That is, afluid gap may form a visually verifiable boundary between cell batchesto reduce diffusion and mixing between electroporated andnon-electroporated cells. Separating cell batches may reduce theduration of time that cells are exposed to certain cytotoxic reagents(e.g., electroporation buffer), thereby increasing performance.

In some variations, a batch of cells may be electroporated whensubstantially static (e.g., substantially no fluid flow state). Bycontrast, conventional continuous flow electroporation has an upperfluid flow rate limit correlated to a transfection efficiency. In thebatch processing described herein, cell batches may be transferred intoand out of the electroporation chamber 7210 at a predetermined rate toincrease the overall throughput of the system 7200 without a decrease inelectroporation efficiency. Furthermore, the electroporation system 7200does not utilize a precisely controlled flow rate/pulse rate such asthose needed for continuous flow electroporation systems.

FIG. 73 is an exploded perspective view of an electroporation module7300 may comprise ah electrode 7310, a fluid conduit 7320 (e.g.,electroporation chamber), a substrate 7330 (e.g. alloy busbar), ahousing 7340, and a fastener 7350. In some variations, the fluid conduit7320 may be configured to hold a volume of fluid between about 0.4 mland about 3.5 ml. The electroporation module 7300 is a parallel-platedesign. In some variations, the electrodes may comprise stainless steeland may be separated by an insulating gasket. In some variations, theelectrodes may be polished and/or coated with nonreactive materials(e.g., gold, platinum) to reduce gradual buildup of biological matter(e.g., charged molecules, DNA, proteins) on the electrode surface.

Generally, a method of electroporating cells may comprise receiving afirst fluid comprising cells in a fluid conduit, receiving a secondfluid in the fluid conduit to separate the first fluid from a thirdfluid, applying an electroporation signal to the first fluid toelectroporate the cells. In some variations, the third fluid may bereceived in the fluid conduit separated from the first fluid by thesecond fluid. In some variations, the first fluid may be substantiallystatic when applying the electroporation signal.

FIGS. 74A-74B are schematic diagrams of variations of an electroporationprocess 7400, 7402. A method 7400 may include loading cells 7410 into anelectroporation chamber 7450. For example, at step 7412, a first fluidmay be pumped into the electroporation by opening valve v1 and the pumpgenerating negative pressure (valves v2 and v3 are closed). At step7414, a second fluid (e.g., gas, oil) may separate the first fluid froma third fluid to create a first batch of cells to electroporate. Forexample, valves v1 and v3 may be closed with valve v2 open and the pumpgenerating negative pressure. In some variations, a loading volume maybe between about 1 ml and about 3 ml with a pumping time of betweenabout 8 seconds and about 15 seconds (at a rate of about 20 ml/min). Atstep 7420, the cells of the first fluid may be electroporated with eachof the valves closed and the pump off. At step 7430, the cells of thefirst fluid may be flowed out of the electroporation chamber 7450 tooutput where valves v1 and v2 are closed, valve v3 is open, and the pumpgenerates positive pressure.

FIG. 74B depicts another configuration where a pump is disposed betweenan input and the electroporation chamber such that the pump may beconfigured to pump in a single direction. A method 7402 may includeloading cells 7411 into an electroporation chamber 7450. For example, atstep 7416, a first fluid may be pumped into the electroporation byopening valve v1 and v4, and the pump generating positive pressure(valves v2 and v3 are closed). At step 7418, a second fluid (e.g., gas,oil) may separate the first fluid from a third fluid to create a firstbatch of cells to electroporate. For example, valves v1 and v3 may beclosed with valves v2 and v4 open, and the pump generating positivepressure. At step 7422, the cells of the first fluid may beelectroporated with each of the valves closed and the pump off. At step7432, the cells of the first fluid may be flowed out of theelectroporation chamber 7450 to output where valves v1 and v4 areclosed, valves v2 and v3 are open, and the pump generates positivepressure.

In some variations, an impedance/resistance across electrodes of anelectroporation system may increase over time due to electrodepassivation/degradation due to charged biological matter (e.g., chargedmolecules, DNA, proteins) attaching to the electrode surface. Activeelectrical field compensation may be applied to ensure a consistentelectrical field strength applied to cells over multiple batches ofcells. This may reduce the need for electrode surface modification toreduce passivation.

FIG. 75 is a circuit diagram of a resistor divider network for anelectroporation process 7500. For example, a set of cells may beintroduced into an electroporation chamber 7510 to which a voltageV_(chip) may be applied. Fluid resistance R_(b) corresponds to a fluid(e.g., cell mixture) resistance. Assuming a uniform cell distribution,the fluid resistance R_(b) should be consistent, also assuming the samevolume of each fluid batch being electroporated. R_(i) corresponds to aresistance between fluid and electrode, which increases over timethrough the electroporation process. In a conventional electroporationprocess, voltage V_(ps) is constant. However, due to the increasingR_(i) over time, the voltage applied to the fluid will decrease overtime, leading to lower electrical field strength.

Due to variations in fluid resistance R_(b) and the low number of pulsesthat may be applied, interpolation to compensate for reduced electricalfield strength may not accurately compensate for electrode passivation.

In some variations, a method of electroporating cells may comprisereceiving a first fluid comprising cells in a fluid conduit, applying aresistance measurement signal to the first fluid using a set ofelectrodes, measuring a resistance between the first fluid and the setof electrodes, and applying an electroporation signal to the first fluidbased on the measured resistance. In some variations, a second fluidcomprising a gas may be received in the fluid conduit before applyingthe electroporation signal to the fluid. The first fluid may beseparated from a third fluid by the second fluid.

FIGS. 76A-76D are plots 7600, 7602, 7604, 7606 of measurement waveformsand electroporation waveforms. FIG. 76A depicts a first resistancemeasurement pulse 7620 with a low voltage and a wide pulse width. FIG.76B depicts a second resistance measurement pulse 7622 with a highvoltage and a short pulse width. FIG. 76C depicts a third resistancemeasurement pulse 7624 with a continuous low voltage waveform to monitoran impedance change continuously over time. FIG. 76D depicts a fourthresistance measurement pulse 7626 with a low AC voltage waveform tomonitor an impedance change continuously over time. Each of theresistance measurement pulses avoid inducing electroporation in thecells by reducing voltage and/or pulse width. By monitoring the voltagecurrent of the applied resistance measurement pulse, a change inresistance may be measured and the electroporation pulse applied to acell batch may be compensated accordingly.

In some variations, an electroporation signal may comprise between about1 pulse and about 50 pulses, a voltage of between about 100 V and about700 V, a pulse width of between about 100 μs and about 1 ms, a pulsespacing between about 5 second to about 30 seconds, a resistance pulsevoltage of between about 10 V and about 40 V, and a resistance pulsewidth of between about 10 μs and about 50 μs.

For example, an eight-batch electroporation run may receive oneelectroporation pulse per batch. Each electroporation pulse may have anelectrical field strength between about 0.5 kV/cm and about 2.0 kV/cm.The resistance measurement pulse applied before each batch may have anelectrical field strength less than about 0.2 kV/cm such thatelectroporation is not induced by the resistance measurement pulse.

Sterile Liquid Transfer Device

Generally, the sterile liquid transfer devices described herein may beconfigured to store fluid for transfer to another component of a cellprocessing system such as a cartridge, bioreactor, and the like. In somevariations, the sterile liquid transfer device may comprise a portableconsumable configured to be moved using a robot. For example, a robotmay be configured to move a sterile liquid transfer device from areagent vault to an ISO 7 space to a sterile liquid transfer instrumentwithin a cell processing system. The sterile liquid transfer deviceenables the transfer of fluids in an automated, sterile, and meteredmanner for automating cell therapy manufacturing.

FIGS. 103A and 103B are perspective views of a sterile liquid transferdevice 10300 comprising a fluid cavity 10310 (e.g., container, vessel),fluid connector 10320 (e.g., fluid connector), and pump 10330. Fluidstored within fluid cavity 10310 may be transferred in and out of thesterile liquid transfer device 10300 through the fluid connector 10320using the pump 10330. In some variations, the sterile liquid transferdevice 10300 may comprise an engagement feature 10340 (e.g., robotmount) to facilitate robotic arm control.

Fluid Connector

Generally, the aseptic fluid connectors described herein may form asterile fluid pathway between at least two fluid devices to enable fluidtransfer that may be one or more of sterile, fully automated, andprecisely metered (e.g., precise control of a transferred fluid volume).In some variations, the robot may be configured to couple a fluidconnector between at least two of the plurality of instruments and oneor more cartridge. In some variations, the robot may be configured tooperate the fluid controller to open and close a set of ports and valvesof the fluid connector. The use of a robot and controller to operate thefluid connector may facilitate automation and sterility of a cellprocessing system.

In some variations, a system may comprise a robot configured to operatea fluid connector as described herein, and a controller comprising amemory and processor. The controller may be coupled to the robot. Thecontroller may be configured to generate a port signal to couple thefirst port to the second port using the robotic arm, generate a firstvalve signal to translate the first valve relative to the second valveusing the robotic arm, and generate a second valve signal to transitionthe first valve and the second valve to the open configuration.

In some variations, a fluid pump may be coupled to the sterilant source,and the controller may be configured to generate a first fluid signal tocirculate a fluid into the chamber through the sterilant port. Thecontroller may be configured to generate a second fluid signal tocirculate the sterilant into the chamber through the sterilant port tosterilize at least the chamber. The controller may be configured togenerate a third fluid signal to remove the sterilant from the chamber.

In some variations, the controller may be configured to generate a portsignal to couple the first port to the second port using the roboticarm, generate a first valve signal to translate the first valve relativeto the second valve using the robotic arm, and generate a second valvesignal to transition the first valve and the second valve to the openconfiguration.

The fluid connector may further allow for a plurality of connectioncycles in a sterile system and may be controlled without humanintervention. For example, the fluid connector may comprise one or moreof engagement features to facilitate robotic arm control and alignmentfeatures to ensure proper connection between connector components. FIG.15 is a block diagram of an illustrative variation of a fluid connectorsystem 1500 comprising a fluid connector 1510, first fluid device 1520,second fluid device 1522, sterilant source 1530, fluid source 1532,robot (e.g., robotic arm) 1540, and controller 1550. The fluid connector1510 may be removably coupled (e.g., connected/disconnected,attached/detached) to each of the first fluid device 1520, second fluiddevice 1522, sterilant source 1532, fluid source 1532, and robot 1540.In some variations, a fluid device may comprise one or more of acartridge and sterile liquid transfer device. For example, a sterileliquid transfer device may be in fluid communication with a cartridgevia the fluid connector. As described in more detail herein, separateportions (e.g., male connector, female connector) of the fluid connector1510 may be removably coupled to each other. The robot 1540 may beconfigured to physically manipulate (e.g., removably couple) one or moreof the fluid connector 1510, first fluid device 1520, second fluiddevice 1522, sterilant source 1530, and fluid source 1532 in apredetermined manner. For example, the robot 1540 may connect the fluidconnector 1510 between the first fluid device 1520 and the second fluiddevice 1522. The robot 1540 may also connect the sterilant source 1530and/or fluid source 1532 to a sterilant port of the fluid connector1510. In some variations, the robot 1540 may control one or more valvesand/or ports of the fluid connector 1510, and thereby initiate asterilization process for one or more portions of the fluid connector1510 using, for example, sterilant from the sterilant source 1530. Thecontroller 1550 may be coupled to one or more of the robot 1540,sterilant source 1530, and fluid source 1532 to control one or more offluid transfer and sterilization.

Generally, to permit transfer of one or more of a cell product (that is,solution(s) containing cell product), fluids, and reagents between themodules, the modules of the cartridge may be fluidically coupled to oneanother either directly or via one or more liquid transfer buses. Insome variations, a liquid transfer bus may comprise a portion of thecartridge configured to control the flow and distribution of the cellproduct between modules and reservoirs. A liquid transfer bus maycomprise one or more of a fluid manifold, fluid conduit (e.g., tubing),and one or more valves (including but not limited to 2/2 valves, 3/2valves, 3/3 valves, 4/2 valves, and rotary selector valves).

Transfer of the cell product, reagents, or fluids within the cartridgemay be achieved by any pump or other structure that generates a pressuredifferential between fluid in one portion of the cartridge and fluid inanother portion of the cartridge. For example, the cartridge maycomprise one or more pump; the cartridge may be pre-loaded withpressurized fluid contained behind a valve; the cartridge may beconnected to a fluid source or a fluid sink. The cartridge may containone or more mechanical pumps (e.g., linear pump, peristaltic pump, gearpump, screw pump, plunger pump) or portions of a pump (i.e. the pump mayinterface with a pump actuator). External pressure may be applied to thecartridge, to tubing within the cartridge, or to a bag within thecartridge (that is, applying pressure either to the liquid in the bag orto headspace gas of the bag). In some variations, an arrangement of thecomponents of the cartridge may facilitate gravity-based fluid transferwithin the cartridge (e.g., gravity-fed pumping). Although one advantageof the disclosed variations may be reduced operator intervention, thesystems and methods of the disclosure may use manual operation in thedesigned workflow or as an adjunct to automated operation in case ofimperfect automated system operation. For example, a process step mayinclude manual intervention, such as fluid input or output. An operatormay intervene in an automated process to correct device operation, (e.g.manually compressing a bag to flush remaining fluid into the system).Fluid may comprise liquid and/or gas, as compressed gases suppliedexternally or provided in pressurized chambers may be used to generateliquid flow, e.g., transfer of solution containing a cell product fromone module to another.

In some variations, the liquid transfer bus may be configured to deliverthe cell product(s) to each of a series of modules in an order set bythe design of the cartridge, or in an order determined by operation ofthe system by the processor or processors. Similarly stated, somevariations of the cartridge may have the advantage that the order ofcell processing steps as well as the process parameters for any of thecell therapy processing steps may not be set by the cartridge but ratherare controlled by the controller. In some variations, the liquidtransfer bus may be controlled to deliver the cell product to themodules in any of various sequences, or to bypass one or more modules(e.g., by configuring the state of the valve(s) attached to the fluidicbus). In some variations, a module may be used more than once in amethod of cell processing. Optionally, the method may compriseperforming one or more wash steps. For example, a counterflowcentrifugal elutriation (CCE) module may be used more than once. In anillustrative method, the method comprises culturing the cell product ina first bioreactor module, transferring the cell product to the CCEmodule to enrich for a desired cell type, transferring the cell productto a second bioreactor module for a second culturing step, washing theCCE module using a wash solution, and transferring the cell product tothe CCE module for a second enrichment step.

In some variations, the liquid transfer bus or the liquid transfer busesmay be fluidically coupled to multiple bags or reservoirs used toprovide solutions or reagents, store cell products, or to collect wastesolutions or reagents.

In some variations, the cartridge may comprise one or more pumps, whichmay be fluidically coupled to the liquid transfer bus and/or one or moremodules. The pump(s) may include a motor operatively coupled to controlcircuits and a power source (e.g. a battery or electrical connectors foran off-cartridge power source). In some variations, the pump may bedivided into a pump on the cartridge and pump actuators on one or moreinstruments of the system. The pump may be an opening in the cartridgewith tubing arranged around the circumference of the opening andconfigured to receive a pump actuator (e.g., a peristaltic rotor). Bydividing components of the pump that contact the cell product (i.e.tubing) from components of the pump that perform operations of the cellproduct, (i.e. the pump actuator, e.g., peristaltic rotor), thecartridge may be compact and simplified. For example, FIG. 26A and FIG.26B illustrate a pump head 2610 and a pump 2610 of a cartridge in anuncoupled configuration (FIG. 13A) and a coupled configuration.

In some variations, one or more pumps 146 (e.g., fluid pump) maygenerate a predetermined fluid flow rate to circulate a sterilant and/orfluid. In some variations, a pump may comprise one or more of a positivedisplacement pump (e.g., peristaltic pump, diaphragm pump, syringepump), centrifugal pump, combinations thereof, and the like. One or morefluid sources may be coupled to the pump.

In some variations, the pump may be configured to receive a pump signal(generated by a controller) configured to circulate a sterilant for adwell time sufficient to sterilize at least a portion of a fluidconnector. For example, the pump may be configured to circulate thesterilant for at least 10 seconds. In some variations, the pump may beconfigured to receive a pump signal configured to circulate anon-sterilant gas (e.g., inert gas, air) to remove the sterilant.

In some variations, a discontinuous flow pump (e.g., peristaltic pump)may generate pulsatile flow as, for example, a tube contracts andrelaxes between rollers. In some variations, closed loop feedback from aflow sensor may be used to compensate for pulsatile flow to generate asubstantially continuous flow rate. For example, a flow sensor may becoupled to a fluid conduit to measure the flow rate. A controller mayreceive the measured flow rate and generate a pump signal to the pumpbased on a proportional correction function configured to reduce the“ripples” measured by the flow sensor. Additionally or alternatively, acontroller may apply periodic error correction to a pump signal toreduce periodic error that may be unique to each pump. For example, aflow sensor may measure and determine a periodic error of a pump. A pumpsignal comprising the periodic error correction may correspond to awaveform comprising an inverse shape of the error. The resulting pumpflow may correct for fluctuations in flow rate.

In some variations, a system 100 may comprise a controller 120 (e.g.,computing device) comprising one or more of a processor 122, memory 124,communication device, 126, input device 128, and display 130.

For example,the methods 9800-10100 described with respect to FIGS. 98-101 may beperformed within the cartridge 10210. In some variations, the system10200 may comprise a sterile liquid transfer device 10220 comprising areagent 10222, and a cartridge 10210 comprising a plurality ofbioreactor modules 10230, a pump module 10240, a thermal module 10245, apressure driven flow module 10250, a MACS module 10255, anelectroporation module 10260, a FACS module 10265, a CCE module 10270,and a blank module 10280. The cartridge 10210 may further comprise areagent storage 10285, a plurality of product bags 10290, and a liquidtransfer bus 10295. The liquid transfer bus 10295 may be configured tocouple the components of the cartridge 10210 for fluid communication.

In some variations, loading and removing of cell product into and out ofthe cartridge may be performed in the system or outside the system. Insome variations, the cartridge is loaded bedside to the patient or donorand then delivered to a cell processing system in or near the hospital,or shipped to a facility where the cell processing system is installed.Likewise, the cell product may be removed from the cartridge afterprocessing either at a facility or closer to the intended recipient ofthe cell product (the patient). Optionally the cell product is frozenbefore, during, or after the methods of the disclosure-optionally afteraddition of one or more cryoprotectants to the cell product. In somevariations, the system comprises a freezer and/or a liquid nitrogensource. In some variations, the system comprises a water bath or awarming chamber containing gas of controlled temperature to permitcontrolled thawing of the cell product, e.g. a water bath set to betweenabout 20° C. and about 40° C. In some variations, the cartridge is madeof materials that resistant mechanical damage when frozen.

Automated Cell Processing

Described here are methods of transforming user-defined cell processingoperations into cell processing steps using the automated cellprocessing systems and devices described herein. In some variations,cell processing operations are received and transformed into cellprocessing steps to be performed by the system given a set ofpredetermined constraints. For example, a user may input a set ofbiologic process steps and corresponding biologic process parameters tobe executed by a cell processing system. Optionally, process parametersmay be customized for each cartridge or sets of cartridges.

FIG. 35 is a flowchart that generally describes a variation of a methodof automated cell processing. The method 3500 may include receiving anordered input list of cell processing operations 3502. For example, aset of more than one ordered input list of cell processing operationsmay be received to be performed on more than one cartridge on anautomated cell processing system. For example, as shown in the GUI 4900of FIG. 49 and described in more detail herein, one or more biologicprocess inputs (e.g., available operations) such as enrichment, MACSselection, activation, transduction, transfection, expansion, and inlineanalysis may be selected as an ordered input list of cell processingoperations. Furthermore, GUI 5200 of FIG. 52 illustrates a completeordered input list of cell processing operations (e.g., set of selectedoperations) 5220 selected by a user.

In some variations, one or more sets of cell processing parameters maybe received 3504. Each set of cell processing parameters may beassociated with one of the cell processing operations. Each set of cellprocessing parameters may specify characteristics of the cell processingstep to be performed by the instrument at that cell processing step. Forexample, the GUI 4000 of FIG. 40 illustrates reagent and containerparameters, the GUI 4200 of FIG. 42 illustrates an example of a processparameter, the GUI 4400 of FIG. 44 illustrates an example of apreprocess analytic, and the GUI 4800 of FIG. 48 illustrates an exampleof a set of activation settings.

In some variations, a transformation model may be executed on theordered input list 3506. In some variations, the transformation modelmay comprise constraints on the ordered output list determined by apredetermined configuration of the automated cell processing system. Forexample, the constraints may comprise information on the configurationof the automated cell processing system.

In some variations, the constraints may comprise one or more of a typeand/or number and/or state of instruments, a type and/or number and/orstate of modules on the cartridge, a type and/or number of reservoirs onthe cartridge, a type and/or number of sterile liquid transfer ports onthe cartridge, and number and position of fluid paths between themodules, reservoirs, and sterile liquid transfer ports on the cartridge.

In some variations, a set of predetermined constraints may be placed ona set of the process control parameters. For example, the volume and/orthe type of reagents used may be constrained based on the size of thesystem and/or products manufactured. Other process parameter constraintsmay include, but is not limited to, one or more or temperature, volume,time, pH, cell size, cell number, cell density, cell viability,dissolved oxygen, glucose levels, volumes of onboard reagent storage andwaste, combinations thereof, and the like. For example, the GUI 4000 ofFIG. 40 depicts that a reagent has a volume per unit of 30 ml and arequired volume of 54 ml, and a consumable container has a volume perunit of 75 ml. The GUI 4800 of FIG. 48 depicts that an activationconcentration is 12 mg/L, an activation culture time is 1600 seconds,activation temperature is 18° C., and a gas mix includes 21% oxygen,78.06% nitrogen, and 0.04% of carbon dioxide. These constraints may beapplied by a transformation model to generate an ordered output list ofcell processing steps that affect how one or more of the robot,instrument, and cartridge are operated and the cell productmanufactured.

In some variations, the order of operations may be constrained based onhardware constraints. For example, the robot may be limited to movingone cartridge at a time. Similarly, an instrument may be constrained tooperating on a predetermined number of cartridges at once.

In some variations, as illustrated in the GUI 4900 of FIG. 49 , a loadproduct operation must be the first operation performed, and may beperformed once for each process. A fill and finish operation may alwaysbe the last operation performed before product completion, and may beperformed once for each process.

In some variation, the system may prevent the user from executing a setof operations in an order that cannot be performed by the system.

In some variations, a notification (e.g., warning, alert) may be outputif a user orders a set of operations in a “non-standard” manner. Forexample, a notification may be output if the same type of operation isrepeated sequentially (e.g., enrichment immediately followed byenrichment). Similarly, a notification may be output if an operation(e.g., selection, activation) is used two times or more within a givenprocess when such an operation is typically used just once in a givenprocess.

In some variations, an output of the transformation model may correspondto an ordered output list of cell processing steps capable of beingperformed by the system 3508. For example, the transformation model maybe executed on the sets of ordered input lists to create the orderedoutput list of cell processing steps. The output list of cell processingsteps may control a robot, cartridge, and one or more instruments.

In some variations, the ordered output list is performed by the systemto control a robot to move one or more cartridges each containing a cellproduct between the instruments 3510. For example, the MACS selectionprocess selected by the user may correspond to the robot 230 of FIG. 2moving the cartridge 250 to the cell selection instrument 216 from, forexample, another instrument. In some variations, the ordered output listmay comprise instructions for a robot to load a cartridge (e.g., singleuse consumable) into the cell processing system (e.g., workcell).Furthermore, the robot may be configured to move the cartridge to afirst instrument position.

In some variations, the ordered output list is further performed by thesystem to control one or more of the instruments to perform one or morecell processing steps on one or more cell products 3512 of a respectivecartridge. For example, the compute server rack 210 (e.g., controller120) may be configured to control an electroporation module 220configured to apply a pulsed electric field to a cell suspension of acartridge 250. In some variations, the ordered output list may compriseinstructions for an instrument (e.g., bioreactor) to process the product(e.g., transfer the cell product from a small bioreactor module to alarge bioreactor module). Furthermore, the instrument may be furtherconfigured to operate under a set of process parameters (e.g., 9 hourduration, pH of 6.7, temperature between 37.3° C. and 37.8° C., mixingmode 3). As another example, the ordered output list may compriseinstructions to operate a sterile liquid transfer module to perform oneor more of removing waste from a cartridge, adding media to thecartridge, and adding a MACS reagent to the cartridge.

In some variations, one or more electronic batch records may begenerated 3514 based on the process parameters and data collected fromsensors during process execution. Batch records generated by the systemmay include process parameters, time logging, sensor measurements fromthe instruments, QC parameters determined by QC instrumentation, andother records.

FIG. 36 is a flowchart that generally describes a variation of a methodof executing a transformation model 3600. In some variations, one ormore biological functions may be generated and output to a user. Forexample, a set of configurable biological function blocks may bedisplayed on a graphical user interface for user selection. The GUI mayenable a user to select and order the biological function blocks anddefine biological control parameters. One or more control parameters ofthe biologic function blocks may be modified by a user if desired. Insome variations, one or more biologic function templates may begenerated comprising a predefined sequence of biological functionblocks. One or more biological control parameters of the biologicfunction templates may be modified by a user if desired.

In some variations, a cell processing system may be configured toreceive and/or store one or more biologic function (e.g., process)inputs from the user 3604. For example, a user may select one or morepredefined biological function templates.

In some variations, a biologic process model (e.g., process definition)may be generated based on the biologic process inputs 3606. In somevariations, a biologic process model may include one or more ofenrichment, isolation, MACS selection, FACS selection, activation,genetic modification, gene transfer, transduction, transfection,expansion, formulation (e.g., harvest, pool), cryopreservation, T celldepletion, rest, tissue digestion, washing, irradiation, co-culture,combinations thereof, and the like.

In some variations, the biologic process model may be transformed intoan instrument execution process model 3608. For example, each biologicalfunction block in the biological process model may correspond to anordered list of cell processing system operations with correspondinghardware control parameters. The instrument execution process model maycomprise the sequence of hardware operations corresponding to thebiologic process model. As described herein, the transformation modelmay comprise one or more constraints.

Optionally, in some variations, a cell processing system may beconfigured to receive and/or store one or more instrument executionprocess inputs from the user 3610. For example, a user may modify thetransformed instrument execution process model if desired. The user mayselect specific hardware components to perform certain steps, modifytiming parameters, and the like.

In some variations, the instrument execution process may be executed togenerate the cell product 3612. For example, the cell processing systemat run-time may process the cell product through the system as definedby the instrument execution process model.

In some variations, an instrument execution process may be executed3612. In some variations, an instrument execution process model may betransformed back into a biologic process model 3614. This progress ofthe biologic process model may be output (e.g., displayed) to a user formonitoring. For example, the instrument execution process model maycomprise one or more references (e.g., pointers) back to the biologicalprocess model so that run-time execution progress may be reportedagainst the biological process model.

In some variations, a cell product may be monitored 3616. For example,the GUIs 5300 and 5400 of respective FIGS. 53 and 54 illustrate sensordata monitored by the system for a plurality of products. For example, anumber of viable cells and a status of a process (e.g., as a function ofpercentage completion) may be graphically illustrated for a user.

In some variations, an electronic record may be generated based on themonitored data 3618. For example, one or more electronic batch recordsmay be generated in compliance with, for example, 21 CFR regulations.

For example, a first workflow 5510 for a first product mayinclude a plurality of biologic processes 5512 executed in apredetermined sequence using corresponding elements 5522 (e.g.,hardware) of the platform 5520. Simultaneously, a second workflow 5530for a second product may execute a predetermined sequence of biologicprocesses 5530 using corresponding elements 5524 of the platform 5520.In this manner, hardware resources of the platform 5520 may beefficiently utilized to increase throughput. In some variations, about2, 3, 4, 5, 6, 7, 8, 9, 10, or more cell products may be manufacturedsimultaneously on the platform 5520.

FIG.16C is a schematic diagram of the fluid connector 1600 where the firstport 216 and second port 226 are in a coupled configuration (e.g. dockedposition) that forms a first seal. In some variations, the firstconnector 1610 and the second connector 1620 may be axially and/orrotationally aligned, and one or more of the connectors 1610, 1620 maybe translated to couple the connectors 1610, 1620 together. In FIG. 16C,the first port 1616 and the second port 1626 are each in a closedconfiguration where the lumens of the respective first connector 1610and second connector 1620 are sealed from the external environment tomaintain sterility of the lumen of the fluid connector 1600.Furthermore, the first valve 1618 and the second valve 1628 are each ina closed configuration that seals the proximal and distal ends of theconnectors from each other. For example, the first valve 1618 in theclosed configuration forms a seal (e.g., barrier) between the firstproximal end 1612 and the first distal end 1614. Similarly, the secondvalve 1628 in the closed configuration forms a seal between the secondproximal end 1622 and the second distal end 1624. In this manner, evenif a portion of a connector is contaminated (e.g., first distal end1614), then the other portions of the fluid connector 1600 (e.g., firstproximal end 1612, second connector 1620) may remain sterile by virtueof one or more of the port seals and valve seals.

The ports may be transitioned to an open configuration such that adistal end of the connectors may be in fluid communication. The method2700 may comprise transitioning the ports to an open configuration 2706.FIG. 16D is a schematic diagram of the fluid connector 1600 where thefirst port 1616 and the second port 1626 are transitioned into an openport configuration to create a shared volume between the valves 1618,1628 that is isolated from the external environment. In FIG. 16D, thefirst valve 1618 and the second valve 1628 are in the closedconfiguration such that the chamber 1615 defines the volume (e.g.,cavity) of the fluid connector 1600 between the first valve 1618 and thesecond valve 1628. That is, the first distal end 1614 is in fluidcommunication with the second distal end 1624. The ports 1616, 1627 maybe received and/or held in respective housings 1617, 1627 in the closedconfiguration. In some variations, a robot may be configured totransition the ports 1616, 1626 between the open configuration and theclosed configuration as described in more detail herein. Additionally oralternatively, the first port 1616 and second port 1626 mayautomatically transition (e.g., mechanically actuate) from the closedconfiguration to the open configuration upon mating the first port 1616to the second port 1626.

In some variations, a fluid may be flowed into the fluid connector toaid sterilization. The method 2700 may comprise flowing fluid (e.g.,liquid, gas) into the fluid connector through the sterilant port 2708.FIG. 16E is a schematic diagram of the fluid connector 1600 where thefirst chamber 1615 receives a fluid such as air at a predeterminedtemperature, pressure, and/or humidity. In some variations, one or moreportions of the fluid connector 1600 may be dehumidified. For example,pressurized hot air may optionally be circulated within chamber 1615 inorder to remove residual fluid, moisture, and raise a temperature of theinner surfaces of the chamber 1615. The circulated fluid may flowthrough housings 1617, 1627 and over inner and/or outer surfaces of theports 1616, 1626.

Generally, sterilization of a fluid connector may comprise one or moresteps of dehumidification, conditioning, decontamination, and aeration(e.g., ventilation). Dehumidification may include removing moisture fromthe fluid connector. Conditioning may include heating the surfaces ofthe fluid connector to be decontaminated in order to preventcondensation and aid sterilization. Decontamination may includecirculating a sterilant through the fluid connector at a predeterminedconcentration, rate, and exposure time. Aeration may include removingthe sterilant from the fluid connector by circulating a gas (e.g.,sterile air) through the fluid connector.

A sterilant may be flowed into the fluid connector to sterilize one ormore portions of the fluid connector. As described in more detailherein, the sterilant may be, for example, vaporized hydrogen peroxide(VHP) and/or ionized hydrogen peroxide (IHP). The method 2700 maycomprise flowing a sterilant into the fluid connector through thesterilant port 2710. FIG. 16F is a schematic diagram of the fluidconnector 1600 where the first chamber 1615 receives the sterilant for apredetermined amount of time (e.g., dwell time). For example, thesterilant may be circulated within the chamber 1615 to sterilize thechamber 1615 of the fluid connector 1600 and any contents disposedtherein (e.g., other fluid, biological material). In some variations,the dwell time may be up to about 10 minutes, and between about 1 minuteto about 10 minutes, including all ranges and sub-values in-between. Insome variations, the vaporized hydrogen peroxide may comprise aconcentration between about 50% and about 70%, including all ranges andsub-values in-between. Additionally or alternatively, one or more of thefirst valve 1618 and the second valve 1628 may be in the openconfiguration such that the sterilant may be circulated through otherportions of the fluid connector 1600 such as first proximal end 1612 andsecond proximal end 1622.

In some variations, the valves may be translated relative to each other.The method 2700 may comprise translating a first valve relative to asecond valve 2712. FIG. 16G is a schematic diagram of the fluidconnector 1600 where the first valve 1618 and second valve 1628 arecoupled to each other (e.g., transfer position). The first valve 1618coupled to the second valve 1628 forms a second seal between the firstconnector 1610 and the second connector 1620.

The valves may be transitioned to an open configuration such that eachend of the fluid connector is in fluid communication. The method 2700may comprise transitioning the first valve and the second valve from aclosed configuration to an open configuration 2714. In some variations,the first valve and the second valve may comprise a spring-loadedshutoff configured to actuate to the open configuration, therebyallowing for fluidic communication between the sterile lumens of thefirst connector 1610 and the second connector 1620. In some variations,each of the first valve 1618 of a first connector 1610 and the secondvalve 1628 of a second connector 1620 may comprise an engagement featuresuch as threading configured to facilitate coupling between the firstvalve 1618 and the second valve 1628. For example, once the second valve1628 is translated to contact the first valve 1618, the engagementfeatures of the valves 1618, 1628 may be coupled (e.g., locked) byrotating (e.g., twisting) one of the first valve 1618 and the secondvalve 1628 to engage their respective threads to each other. Conversely,one of the first valve 1618 and the second valve 1628 may be rotated inthe opposite direction to uncouple (e.g., unlock) the first valve 1618from the second valve 1628.

In some variations, fluid may flow through the fluid connector 2716.FIG. 16H is a schematic diagram of the fluid connector depicted in FIG.16A transferring fluid between fluid devices coupled to the fluidconnector. For example, the contents (e.g., fluid, biological material)of the first fluid device 1630 and the second fluid device 1640 may betransferred through the fluid connector 1600. In some variations, one ormore of a pump, gravity feed, and the like may aid transfer through thefluid connector 1600.

In some variations, another fluid may be flowed into the fluid connectorafter fluid transfer between a first fluid device and a second fluiddevice has been completed. The method 2700 may comprise flowing fluid(e.g., liquid, gas, sterilant) into the fluid connector through thesterilant port 2708 to remove a fluid and/or biological material fromthe fluid connector 2718. For example, flowing an inert gas into thefluid connector may reduce drops of liquid from forming when the firstconnector and second connector are separated. If a sterilant is flowedthrough the fluid connector, another fluid such as an inert gas may beflowed to aerate the fluid connector and ensure that the sterilant isremoved.

To begin decoupling the fluid connector, the valves may be translatedaway from each other. The method 2700 may comprise decoupling the firstconnector and the second connector 2720. In some variations, a robot maybe configured to manipulate the fluid connector 1600 to transition thevalves 1618, 1628 to a closed configuration and to translate the valves1618, 1628 away from each other, which may occur simultaneously orindependently. The valves 1618, 1628 in the closed configuration inhibitfluid flow between the first connector 1610 and the second connector1620. FIG. 16I is a schematic diagram of the fluid connector 1600 in aclosed valve configuration where the second valve 1628 is translatedaway from the first valve 1618. Accordingly, the fluid connector 1600returns to the docked position. For example, the first valve 1618 andthe second valve 1628 may be configured to engage their respectivespring-loaded shutoff features to form a seal and reduce drips and/orleaks. In some variations, one or more of a fluid and sterilant mayoptionally be configured to circulate through the chamber 1615 to removemoisture and/or sterilize the chamber 1615.

FIG. 16J is a schematic diagram of the fluid connector 1600 where thefirst port 1616 and the second port 1626 are transitioned from the openport configuration to the closed port configuration. In some variations,a robot may be configured to manipulate the fluid connector 1600 totransition the ports 1616, 1626 to a closed position to seal a lumen ofthe first connector 1610 from a lumen of the second connector 1620. Insome variations, the ports 1616, 1626 may be configured to automaticallytransition to the closed port configuration when the first valve 1618separates from the second valve 1628.

FIG. 16K is a schematic diagram of the fluid connector 1600 where thesecond connector 1620 is translated away from the first connector 1610.In some variations, a robot may be configured to manipulate the fluidconnector 1600 to separate the first connector 1610 from the secondconnector 1620. FIG. 16K depicts the fluid connector 1600 in adisengaged configuration.

FIG. 16L is a schematic diagram of the fluid connector 1600 decoupledfrom the sterilant source. In some variations, a robot may be configuredto manipulate the fluid connector 1600 and/or sterilant source toseparate the sterilant source 1650 from the sterilant source. In somevariations, the sterilant source may be decoupled from the fluidconnector 1600 at any point after completing a sterilization process.

In some variations, the cartridge comprises one or more Sterile LiquidTransfer Ports (SLTPs) configured for use with a Sterile Liquid TransferDevice (SLTD). In some variations, the SLTP comprises one or more of acap, a fitting, and a tube fluidically coupled to the fitting. The capmay be removable or pierceable. The fitting may be a push-to-connectfitting (PTCF) or a threaded fitting. PTCF include male-to-female,female-to-male, and androgynous fittings. Illustrative SLTPs and SLTDssuitable for use in the systems of the disclosure may include, forexample, AseptiQuik® S connectors, Lynx® CDR connectors, Kleenpak™connectors, Intact™ connectors, GE LifeScience® ReadyMate connectors.

When the disclosure refers to sterile liquid transfer devices, sterileliquid transfer ports, and sterile liquid transfer, the word “sterile”should be understood as a non-limiting description of some variations—anoptional feature providing advantages in operation of certain systemsand methods of the disclosure. Maintaining sterility is typicallydesirable for cell processing but may be achieved in various ways,including but not limited to providing sterile reagents, media, cells,and other solutions; sterilizing cartridge(s) and/or cartridgecomponent(s) after loading (preserving the cell product fromdestruction); and/or operating the system in a sterile enclosure,environment, building, room, or the like. Such operator performed orsystem performed sterilization steps may make the cartridge or cartridgecomponents sterile and/or preserve the sterility of the cartridge orcartridge components.

Fluidmay flow through the first connector 8910 and into the second connector8920 via a lumen of needle 8990. Each of the elastomeric members 8970,8980 and thermal members 8972, 8982 may seal once the needle 8990 iswithdrawn from a distal end of the first connector 8910. For example,the thermal member 8972, 8982 may be configured to thermally seal at apredetermined temperature and the elastomeric members 8970, 8980 mayself-seal once the needle 8990 has been withdrawn. In some variations,the fluid connector 8900 may be thermally decontaminated and resealedafter fluid transfer.
